                                   ARTICLE 2.
                                    THE NOTES

Section 2.01 Form and Dating.

      (a)   General. The Notes and the Trustee's certificate of authentication
will be substantially in the form of Exhibit A or Exhibit B, as applicable. The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. Each Note will be dated the date of its authentication.
The Notes shall be in denominations of $1,000 and integral multiples thereof.

      The terms and provisions contained in the Notes will constitute, and are
hereby expressly made, a part of this Indenture and the Issuers and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any provision of
any Note conflicts with the express provisions of this Indenture, the provisions
of this Indenture shall govern and be controlling.

      (b)   Global Notes. Notes issued in global form will be substantially in
the form of Exhibit A or Exhibit B, as applicable (including the Global Note
Legend thereon and the "Schedule of Exchanges of Interests in the Global Note"
attached thereto). Notes issued in definitive form will be substantially in the
form of Exhibit A (but without the Global Note Legend thereon and without the
"Schedule of Exchanges of Interests in the Global Note" attached thereto). Each
Global Note will represent such of the outstanding Notes as will be specified
therein and each shall provide that it represents the aggregate principal amount
of outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented
thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required
by Section 2.06.

      (c)   Temporary Global Notes. Notes offered and sold in reliance on
Regulation S will be issued initially in the form of the Regulation S Temporary
Global Note, which will be deposited on behalf of the purchasers of the Notes
represented thereby with the Trustee, at its corporate trust office, as
Custodian, and registered in the name of the Depositary or the nominee of the
Depositary for the accounts of designated agents holding on behalf of Euroclear
or Clearstream, duly executed by the Issuers and authenticated by the Trustee as
hereinafter provided. The Restricted Period will be terminated upon the receipt
by the Trustee of (1) a written certificate from the Depositary, together with
copies of certificates from Euroclear and Clearstream, certifying that they have
received certification of non-United States beneficial ownership of 100% of the
aggregate principal amount of the Regulation S Temporary Global Note (except to
the extent of any beneficial owners thereof who acquired an interest therein
during the Restricted Period pursuant to another exemption from registration
under the Securities Act and who will take delivery of a beneficial ownership
interest in a 144A Global Note or an IAI Global Note bearing a

                                       44
<PAGE>

Private Placement Legend, all as contemplated fay Section 2.06(b)), and (2) an
Officer's Certificate from the Company stating that such Restricted Period has
ended.

      Following the termination of the Restricted Period, beneficial interests
in the Regulation S Temporary Global Note will be exchanged for beneficial
interests in Regulation S Permanent Global Notes pursuant to the Applicable
Procedures. Simultaneously with the authentication of Regulation S Permanent
Global Notes, the Trustee will, upon receipt of written directions, cancel the
Regulation S Temporary Global Note. The aggregate principal amount of the
Regulation S Temporary Global Note and the Regulation S Permanent Global Notes
may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depositary or its nominee, as the case may be, in
connection with transfers of interest as hereinafter provided.

      (d)   Euroclear and Clearstream Procedures Applicable. The provisions of
the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Clearstream
Banking" and "Customer Handbook" of Clearstream will be applicable to transfers
of beneficial interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by Participants through
Euroclear or Clearsteam.

Section 2.02 Execution and Authentication.

      One Officer of each Issuer must sign the Notes for the Issuers by manual
or facsimile signature.

      If an Officer whose signature is on a Note no longer holds that office at
the time a Note is authenticated, the Note will nevertheless be valid.

      A Note will not be valid until authenticated by the manual signature of
the Trustee. The signature will be conclusive evidence that the Note has been
authenticated under this Indenture.

      The Trustee will, upon receipt of a written order of the Issuers signed by
one Officer of each Issuer (an "Authentication Order") authenticate Notes for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed such amount except as provided in Section 2.07.

      The Trustee may appoint an authenticating agent acceptable to the Issuers
to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

      The Company, on behalf of itself and CalGen Finance, will maintain an
office or agency where Notes may be presented for registration of transfer or
for exchange ("Registrar") and an office or agency where Notes may be presented
for payment ("Paying Agent"). The Registrar will keep a register of the Notes
and of their transfer and exchange. The Issuers may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent. The Issuers may change any Paying Agent or Registrar without
notice to any Holder. The Company will notify the Trustee in writing of the name
and address of any Agent not a party to this Indenture. If the Issuers fail to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.

                                       45
<PAGE>

      The Issuers initially appoint The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Notes.

      The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

      The Issuers will require each Paying Agent other than the Trustee to agree
in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal
of, or premium, if any, interest or Special Interest, if any, on, the Notes, and
will notify the Trustee of any default by the Issuers in making any such
payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) will have no further liability for the money. If the Company or a
Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon
any bankruptcy or reorganization proceedings relating to the Company, the
Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

      The Trustee will preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee
is not the Registrar, the Company will furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders and the
Company shall otherwise comply with TIA Section 312(a).

Section 2.06 Transfer and Exchange.

      (a)   Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. A Global Note will be exchangeable by
the Issuers for Definitive Notes if:

            (1)   the Issuers deliver to the Trustee written notice from the
      Depositary that it is unwilling or unable to continue to act as Depositary
      or that it is no longer a clearing agency registered under the Exchange
      Act and, in either case, a successor Depositary is not appointed by the
      Issuers within 120 days after the date of such notice from the Depositary;

            (2)   the Issuers in their sole discretion determine that the Global
      Notes (in whole but not in part) should be exchanged for Definitive Notes
      and deliver a written notice to such effect to the Trustee; provided, that
      in no event shall the Regulation S Temporary Global Note be exchanged by
      the Issuers for Definitive Notes prior to (x) the expiration of the
      Restricted Period and (y) the receipt by the Registrar of any certificates
      required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

            (3)   there has occurred and is continuing a Default or
      Event of Default with respect to the Notes.

                                       46
<PAGE>

      Upon the occurrence of any of the preceding events in (1), (2) or (3)
above, Definitive Notes shall be issued in such names as the Depositary shall
instruct the Trustee in writing. Global Notes also may be exchanged or replaced,
in whole or in part, as provided in Sections 2.07 and 2.10. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10, shall be
authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this
Section 2.06(a); however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(b), (c) or (f).

      (b)   Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes will be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes will be subject to restrictions on transfer comparable to those set
forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also will require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

            (1)   Transfer of Beneficial Interests in the Same Global Note.
      Beneficial interests in any Restricted Global Note may be transferred to
      Persons who take delivery thereof in the form of a beneficial interest in
      the same Restricted Global Note in accordance with the transfer
      restrictions set forth in the Private Placement Legend; provided, however,
      that prior to the expiration of the Restricted Period, transfers of
      beneficial interests in the Regulation S Temporary Global Note may not be
      made to a U.S. Person or for the account or benefit of a U.S. Person
      (other than the Initial Purchaser). Beneficial interests in any
      Unrestricted Global Note may be transferred to Persons who take delivery
      thereof in the form of a beneficial interest in an Unrestricted Global
      Note. No written orders or instructions shall be required to be delivered
      to the Registrar to effect the transfers described in this Section
      2.06(b)(1).

            (2)   All Other Transfers and Exchanges of Beneficial Interests in
      Global Notes. In connection with all transfers and exchanges of beneficial
      interests that are not subject to Section 2.06(b)(1) above, the transferor
      of such beneficial interest must deliver to the Registrar either:

                  (A)   both:

                        (i)   a written order from a Participant or an Indirect
                  Participant given to the Depositary in accordance with the
                  Applicable Procedures directing the Depositary to credit or
                  cause to be credited a beneficial interest in another Global
                  Note in an amount equal to the beneficial interest to be
                  transferred or exchanged; and

                        (ii)  instructions given in accordance with the
                  Applicable Procedures containing information regarding the
                  Participant account to be credited with such increase; or

                  (B)   both:

                        (i)   a written order from a Participant or an Indirect
                  Participant given to the Depositary in accordance with the
                  Applicable Procedures directing the Depositary to cause to be
                  issued a Definitive Note in an amount equal to the beneficial
                  interest to be transferred or exchanged; and

                                       47
<PAGE>

                        (ii)  instructions given by the Depositary to the
                  Registrar containing information regarding the Person in whose
                  name such Definitive Note shall be registered to effect the
                  transfer or exchange referred to in (1) above;

                  provided, that in no event shall Definitive Notes be issued
                  upon the transfer or exchange of beneficial interests in the
                  Regulation S Temporary Global Note prior to (A) the expiration
                  of the Restricted Period and (B) the receipt by the Registrar
                  of any certificates required pursuant to Rule 903 under the
                  Securities Act.

      Upon consummation of an Exchange Offer by the Company in accordance with
      Section 2.06(f) hereof, the requirements of this Section 2.06(b)(2) shall
      be deemed to have been satisfied upon receipt by the applicable exchange
      agent of (i) the instructions contained in the Letter of Transmittal
      delivered by the Holder of such beneficial interests in the Restricted
      Global Notes or (ii) the instructions contained in the agent's message
      received by such exchange agent through DTC's Automated Tender Offer
      Procedures, as applicable. Upon satisfaction of all of the requirements
      for transfer or exchange of beneficial interests in Global Notes contained
      in this Indenture and the Notes or otherwise applicable under the
      Securities Act, the Trustee shall adjust the principal amount of the
      relevant Global Note(s) pursuant to Section 2.06(h) hereof.

            (3)   Transfer of Beneficial Interests to Another Restricted Global
      Note. A beneficial interest in any Restricted Global Note may be
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in another Restricted Global Note if the transfer
      complies with the requirements of Section 2.06(b)(2) above and the
      Registrar receives the following:

                  (A)   if the transferee will take delivery in the form of a
            beneficial interest in the 144A Global Note, then the transferor
            must deliver a certificate in the form of Exhibit C, including the
            certifications in item (1) thereof;

                  (B)   if the transferee will take delivery in the form of a
            beneficial interest in the Regulation S Temporary Global Note or the
            Regulation S Global Note, then the transferor must deliver a
            certificate in the form of Exhibit C, including the certifications
            in item (2) thereof; and

                  (C)   if the transferee will take delivery in the form of a
            beneficial interest in the IAI Global Note, then the transferor must
            deliver a certificate in the form of Exhibit C, including the
            certifications, certificates and Opinion of Counsel required by item
            (3) thereof, if applicable.

            (4)   Transfer and Exchange of Beneficial Interests in a Restricted
      Global Note for Beneficial Interests in an Unrestricted Global Note. A
      beneficial interest in any Restricted Global Note may be exchanged by any
      holder thereof for a beneficial interest in an Unrestricted Global Note or
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in an Unrestricted Global Note if the exchange or
      transfer complies with the requirements of Section 2.06(b)(2) above and:

                  (A)   such exchange or transfer is effected pursuant to the
            Exchange Offer in accordance with the Registration Rights Agreement
            and the holder of the beneficial interest to be transferred, in the
            case of an exchange, or the transferee, in the case of a transfer,
            certifies in the applicable Letter of Transmittal that it is not (i)
            a Broker-Dealer, (ii) a Person participating in the distribution of
            the Exchange Notes or (iii) a Person who is an affiliate (as defined
            in Rule 144) of the Company;

                                       48
<PAGE>

                  (B)   such transfer is effected pursuant to the Shelf
            Registration Statement in accordance with the Registration Rights
            Agreement;

                  (C)   such transfer is effected by a Broker-Dealer pursuant to
            the Exchange Offer Registration Statement in accordance with the
            Registration Rights Agreement; or

                  (D)   the Registrar receives the following:

                        (i)   if the holder of such beneficial interest in a
                  Restricted Global Note proposes to exchange such beneficial
                  interest for a beneficial interest in an Unrestricted Global
                  Note, a certificate from such holder in the form of Exhibit D,
                  including the certifications in item (1)(a) thereof; or

                        (ii)  if the holder of such beneficial interest in a
                  Restricted Global Note proposes to transfer such beneficial
                  interest to a Person who shall take delivery thereof in the
                  form of a beneficial interest in an Unrestricted Global Note,
                  a certificate from such holder in the form of Exhibit C,
                  including the certifications in item (4) thereof;

            and, in each such case set forth in this subparagraph (D), if the
            Registrar so requests or if the Applicable Procedures so require, an
            Opinion of Counsel in form reasonably acceptable to the Registrar to
            the effect that such exchange or transfer is in compliance with the
            Securities Act and that the restrictions on transfer contained
            herein and in the Private Placement Legend are no longer required in
            order to maintain compliance with the Securities Act.

            If any such transfer is effected pursuant to subparagraph (B) or (D)
      above at a time when an Unrestricted Global Note has not yet been issued,
      the Company shall issue and, upon receipt of an Authentication Order in
      accordance with Section 2.02, the Trustee shall authenticate one or more
      Unrestricted Global Notes in an aggregate principal amount equal to the
      aggregate principal amount of beneficial interests transferred pursuant to
      subparagraph (B) or (D) above.

            Beneficial interests in an Unrestricted Global Note cannot be
      exchanged for, or transferred to Persons who take delivery thereof in the
      form of, a beneficial interest in a Restricted Global Note.

      (c)   Transfer or Exchange of Beneficial Interests for Definitive Notes.

            (1)   Beneficial Interests in Restricted Global Notes to Restricted
      Definitive Notes. If any holder of a beneficial interest in a Restricted
      Global Note proposes to exchange such beneficial interest for a Restricted

      (h)   Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note will be returned to or
retained and canceled by the Trustee in accordance with Section 2.11. At any
time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note or for Definitive Notes,
the principal amount of Notes represented by such Global Note will be reduced
accordingly and an endorsement will be made on such Global Note by the Trustee
or by the Depositary at the direction of the Trustee to reflect such reduction;
and if the beneficial interest is being exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in another
Global Note, such other Global Note will be increased accordingly and an
endorsement will be made on such Global Note by the Trustee or by the Depositary
at the direction of the Trustee to reflect such increase.

      (i)   General Provisions Relating to Transfers and Exchanges.

            (1)   To permit registrations of transfers and exchanges, the
      Issuers will execute and the Trustee will authenticate Global Notes and
      Definitive Notes upon receipt of an Authentication Order in accordance
      with Section 2.02 or at the Registrar's request.

                                       57
<PAGE>

            (2)   No service charge will be made to a Holder of a Global Note or
      to a Holder of a Definitive Note for any registration of transfer or
      exchange, but the Issuers may require payment of a sum sufficient to cover
      any transfer tax or similar governmental charge payable in connection
      therewith (other than any such transfer taxes or similar governmental
      charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06,
      3.09, 4.10, 4.15 and 9.05).

            (3)   The Registrar will not be required to register the transfer of
      or exchange any Note selected for redemption in whole or in part, except
      the unredeemed portion of any Note being redeemed in part.

            (4)   All Global Notes and Definitive Notes issued upon any
      registration of transfer or exchange of Global Notes or Definitive Notes
      will be the valid obligations of the Issuers, evidencing the same debt,
      and entitled to the same benefits under this Indenture, as the Global
      Notes or Definitive Notes surrendered upon such registration of transfer
      or exchange.

            (5)   The Issuers will not be required:

                  (A)   to issue, to register the transfer of or to exchange any
            Notes during a period beginning at the opening of business 15 days
            before the day of any selection of Notes for redemption under
            Section 3.02 and ending at the close of business on the day of
            selection;

                  (B)   to register the transfer of or to exchange any Note
            selected for redemption in whole or in part, except the unredeemed
            portion of any Note being redeemed in part; or

                  (C)   to register the transfer of or to exchange a Note
            between a record date and the next succeeding interest payment date.

            (6)   Prior to due presentment for the registration of a transfer of
      any Note, the Trustee, any Agent and the Issuers may deem and treat the
      Person in whose name any Note is registered as the absolute owner of such
      Note for the purpose of receiving payment of principal of and interest on
      such Note and for all other purposes, and none of the Trustee, any Agent,
      the Company or CalGen Finance shall be affected by notice to the contrary.

            (7)   The Trustee will authenticate Global Notes and Definitive
      Notes in accordance with the provisions of Section 2.02.

            (8)   All certifications, certificates and Opinions of Counsel
      required to be submitted to the Registrar pursuant to this Section 2.06 to
      effect a registration of transfer or exchange may be submitted by
      facsimile.

Section 2.07 Replacement Notes.

      If any mutilated Note is surrendered to the Trustee or the Issuers and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Issuers will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements hereunder are met. If required by the Trustee or either Issuer, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent
and any authenticating agent from any loss that any of them may suffer if a Note
is replaced. The Issuers may charge the applicable Holder for their expenses in
replacing a Note.

                                       58
<PAGE>

      Every replacement Note is an additional obligation of the Issuers and will
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

      The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section as
not outstanding. Except as set forth in Section 2.09, a Note does not cease to
be outstanding because the Company or an Affiliate of the Company holds the
Note.

      If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser.

      If the principal amount of any Note is considered paid under Section 4.01,
it ceases to be outstanding and interest on it ceases to accrue.

      If the Paying Agent (other than the Company, a Subsidiary of the Company
or an Affiliate of any thereof) holds, on a redemption date or maturity date,
money sufficient to pay Notes payable on that date, then on and after that date
such Notes will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09 Treasury Notes.

      In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, will be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee will be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

      Until certificates representing Notes are ready for delivery, the Issuers
may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

      Holders of temporary Notes will be entitled to all of the benefits of this
Indenture.

Section 2.11 Cancellation.

      The Issuers at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent will forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. Upon receipt of
written directions, the Trustee and no one else will cancel all Notes
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and will destroy canceled Notes (subject to the record retention
requirement of the Exchange Act). Certification of the destruction of all
canceled Notes will be delivered to the Issuers. The Issuers may not issue new
Notes to replace Notes that they have paid or that have been delivered to the
Trustee for cancellation.

                                       59
<PAGE>

Section 2.12 Defaulted Interest.

      If the Company defaults in a payment of interest on the Notes, it will pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01. The Company will notify the Trustee in writing of the
amount of defaulted interest proposed to be paid on each Note and the date of
the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date, provided, that no such special record date
may be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) will mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

Section 2.13 Same Day Settlement and Payment.

      The Issuers will make payments in respect of the Notes represented by the
Global Notes (including principal, premium, if any, and interest and Special
Interest, if any) by wire transfer of immediately available funds to the
accounts specified by the Holder of the Global Note. The Issuers will make all
payments of principal, interest and premium and Special Interest, if any, with
respect to Definitive Notes by wire transfer of immediately available funds to
the accounts specified by the Holders of the Definitive Notes or, if no such
account is specified, by mailing a check to each such Holder's registered
address.

      Because of time zone differences, the securities account of a Euroclear or
Clearstream participant purchasing an interest in a Global Note from a
Participant in DTC will be credited, and any such crediting will be reported to
the relevant Euroclear or Clearstream participant, during the securities
settlement processing day (which must be a business day for Euroclear and
Clearstream) immediately following the settlement date of DTC. DTC has advised
the Issuers that cash received in Euroclear or Clearstream as a result of sales
of interests in a Global Note by or through a Euroclear or Clearstream
participant to a Participant in DTC will be received with value on the
settlement date of DTC but will be available in the relevant Euroclear or
Clearstream cash account only as of the business day for Euroclear or
Clearstream following DTC's settlement date.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

Section 3.01 [Reserved]

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

      If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee will select Notes for redemption or
purchase on a pro rata basis except:

            (1) if the Notes are listed on any national securities exchange, in
      compliance wife the requirements of the principal national securities
      exchange on which the Notes are listed; or

            (2) if otherwise required by law.

      In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased will be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior

                                       60

<PAGE>

to the redemption or purchase date by the Trustee from the outstanding Notes not
previously called for redemption or purchase.

      The Trustee will promptly notify the Company in writing of the Notes
selected for redemption or purchase and, in the case of any Note selected for
partial redemption or purchase, the principal amount thereof to be redeemed or
purchased. Notes and portions of Notes selected will be in amounts of $1,000 or
whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed or purchased, the entire outstanding amount of Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except
as provided in the preceding sentence, provisions of this Indenture that apply
to Notes called for redemption or purchase also apply to portions of Notes
called for redemption or purchase.

Section 3.03 Notice of Redemption.

      Subject to the provisions of Section 3.09, at least 30 days but not more
than 60 days before a redemption date, the Company will mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may
be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Article 8 or 12 of this Indenture. Notices of
redemption may not be conditional.

      The notice will identify the Note(s) to be redeemed and will state:

            (1)   the redemption date;

            (2)   the redemption price;

            (3)   if any Note is to be redeemed in part only, the portion of the
      principal amount of such Note to be redeemed and that, after the
      redemption date upon surrender of such Note, a new Note or Notes in
      principal amount equal to the unredeemed portion will be issued upon
      cancellation of the original Note;

            (4)   the name and address of the Paying Agent;

            (5)   that Notes called for redemption must be surrendered to the
      Paying Agent to collect the redemption price;

            (6)   that, unless the Issuers default in making such redemption
      payment, interest on Notes called for redemption ceases to accrue on and
      after the redemption date;

            (7)   the paragraph of the Notes and/or Section of this Indenture
      pursuant to which the Notes called for redemption are being redeemed; and

            (8)   that no representation is made as to the correctness or
      accuracy of the CUSIP number, if any, listed in such notice or printed on
      the Notes.

      At the Company's request, the Trustee will give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
has delivered to the Trustee, at least 45 days prior to the redemption date, an
Officer's Certificate requesting that the Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding
paragraph.

                                       61
<PAGE>

Section 3.04 Effect of Notice of Redemption.

      Once notice of redemption is mailed in accordance with Section 3.03, Notes
called for redemption become irrevocably due and payable on the redemption date
at the redemption price. A notice of redemption may not be conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

      Not less than one Business Day prior to the redemption or purchase price
date, the Issuers will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest and
Special Interest, if any, on all Notes to be redeemed or purchased on that date.
The Trustee or the Paying Agent will promptly return to the Issuers any money
deposited with the Trustee or the Paying Agent by the Issuers in excess of the
amounts necessary to pay the redemption or purchase price of, and accrued
interest and Special Interest, if any, on, all Notes to be redeemed or
purchased.

      If the Issuers comply with the provisions of the preceding paragraph, on
and after the redemption or purchase date, interest will cease to accrue on the
Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be
paid. If any Note called for redemption or purchase is not so paid upon
surrender for redemption or purchase because of the failure of the Issuers to
comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption or purchase date until such principal is paid,
and to the extent lawful on any interest not paid on such unpaid principal, in
each case at the rate provided in the Notes and in Section 4.01.

Section 3.06 Notes Redeemed or Purchased in Part.

      Upon surrender of a Note that is redeemed or purchased in part, the
Issuers will issue and, upon receipt of an Authentication Order, the Trustee
will authenticate for the Holder, at the expense of the Company, a new Note
equal in principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

Section 3.07 Optional Redemption.

      The Notes are-not redeemable at the option of the Issuers.

Section 3.08 Mandatory Redemption.

      The Issuers are not required to make mandatory redemption or sinking fund
payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Net Proceeds.

      In the event that, pursuant to Section 4.10, the Issuers are required or
elect to commence an Asset Sale Offer, they will follow the procedures specified
below.

      Within 30 days following the receipt by the Company or any of its
Subsidiaries of Net Proceeds from an Asset Sale, Casualty Event or Condemnation
Event, in the case of an Asset Sale Offer described in clause (1) of the second
paragraph of Section 4.10, or upon completion of a prior required Asset Sale
Offer (and any associated mandatory purchase, prepayment or redemption), in the
case of an Asset Sale Offer described in clause (2) or (3) of the second
paragraph of Section 4.10, the Issuers will mail a notice

                                       62
<PAGE>

to the Trustee and each Holder regarding such Asset Sale Offer. The notice will
contain all instructions and materials necessary to enable the Holders to tender
Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms
of the Asset Sale Offer, will state:

            (1)   that the Asset Sale Offer is being made pursuant to this
      Section 3.09 and Section 4.10;

            (2)   the amount of Net Proceeds being offered to purchase Notes and
      other Third Priority Lien Obligations (the "Offer Amount"), the purchase
      price and the date on which the purchase will be made (the "Purchase
      Date"), which date will be no earlier than 30 and no later than 60 days
      from the date the notice is mailed;

            (3)   that any Note not tendered or accepted for payment will
      continue to accrue interest;

            (4)   that, unless the Issuers default in making such payment, any
      Note accepted for payment pursuant to the Asset Sale Offer will cease to
      accrue interest after the Purchase Date;

            (5)   that Holders electing to have a Note purchased pursuant to an
      Asset Sale Offer may elect to have Notes purchased in integral multiples
      of $1,000 only;

            (6)   that Holders electing to have a Note purchased pursuant to any
      Asset Sale Offer will be required to surrender the Note, with the form
      entitled "Option of Holder to Elect Purchase" on the reverse of the Note
      completed, or transfer by book-entry transfer, to the Company, the
      Depositary or the Paying Agent at the address specified in the notice at
      least three Business Days before the Purchase Date;

            (7)   that Holders will be entitled to withdraw their election if
      the Company, the Depositary or the Paying Agent, as the case may be,
      receives, not later than two Business Days before the Purchase Date, a
      facsimile transmission or letter setting forth the name of the Holder, the
      principal amount of the Note the Holder delivered for purchase and a
      statement that such Holder is withdrawing his election to have such Note
      purchased;

            (8)   that, if the aggregate principal amount of Notes and other
      Third Priority Lien Obligations tendered in the Asset Sale Offer (or
      required to be purchased, prepaid or redeemed) exceeds the Offer Amount,
      the Company will select the Notes and other Third Priority Lien
      Obligations to be purchased, prepaid or redeemed on a pro rata basis based
      on the principal amount of Notes and such other Third Priority Lien
      Obligations tendered (or required to be purchased, prepaid or redeemed),
      with such adjustments as may be deemed appropriate by the Company so that
      only Notes in denominations of $1,000, or integral multiples thereof, will
      be purchased, prepaid or redeemed; and

            (9)   that Holders whose Notes were purchased only in part will be
      issued new Notes equal in principal amount to the unpurchased portion of
      the Notes surrendered (or transferred by book-entry transfer).

      On or before the Purchase Date, the Issuers will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes and other Third Priority Lien Obligations or portions thereof
tendered pursuant to the Asset Sale Offer (or required to be purchased, prepaid
or redeemed), or if less than the Offer Amount has been tendered (or is required
to be purchased, prepaid or redeemed), all Notes and other Third Priority Lien
Obligations tendered (or required to be

                                       63
<PAGE>

purchased, prepaid or redeemed), and will deliver or cause to be delivered to
the Trustee the Notes properly accepted together with an Officer's Certificate
stating that such Notes or portions thereof were accepted for payment by the
Issuers in accordance with the terms of this Section 3.09. Payment for any Notes
so purchased will be made in the same manner as interest payments are made. The
Issuers, the Depositary or the Paying Agent, as the case may be, will promptly
(but in any case not later than five days after the Purchase Date) mail or
deliver to each tendering Holder an amount equal to the purchase price of the
Notes tendered by such Holder and accepted by the Issuers for purchase, and the
Issuers will promptly issue a new Note, and the Trustee, upon written request
from the Issuers, will authenticate and mail or deliver (or cause to be
transferred by book entry) such new Note to such Holder, in a principal amount
equal to any unpurchased portion of the Note surrendered. Any Note not so
accepted shall be promptly mailed or delivered by the Issuers to the Holder
thereof. The Issuers will publicly announce the results of the Asset Sale Offer
on the Purchase Date.

      If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Special Interest, if any, will be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

      The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each

      The Company will maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
fails to maintain any such required office or agency or fails to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

      The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission will in any manner relieve the Company of
its obligation to maintain an office or agency in the Borough of Manhattan, the
City of New York for such purposes. The Company will give prompt written notice
to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

      The Company hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03.

            (1)   all quarterly and annual reports that would be required to be
      filed with the SEC on Forms 10-Q and 10-K if the Company were required to
      file such reports; and

            (2)   all current reports that would be required to be filed with
      the SEC on Form 8-K if the Company were required to file such reports.

following consummation of the Exchange Offer contemplated by the Registration
Rights Agreement, the Company will file a copy of each of the reports referred
to in clauses (1) and (2) above with the SEC for public availability within the
time periods specified in the rules and regulations applicable to such reports
(unless the SEC will not accept such a filing or the Company has elected to pay
Special Interest in lieu of complying with the registration requirements of the
Registration Rights Agreement) and will post the reports on its website within
those time periods.

      If the Company is not subject to the periodic reporting requirements of
the Exchange Act for any reason, the Company will nevertheless file the reports
specified in the preceding paragraphs of this covenant with the SEC within the
time periods specified above unless the SEC will not accept such a filing or the
Company has elected to pay Special Interest in lieu of complying with the
registration requirements of the Registration Rights Agreement. However, if the
Company does not file any such reports with the SEC, the Company will post the
reports referred to in the preceding paragraphs on its website within the time
periods that would apply if the Company were required to file those reports with

      In addition, the Company and the Guarantors agree that, for so long as any
Notes remain

her knowledge the Company has kept, observed, performed and fulfilled each and

not in default in the performance or observance of any of the terms, provisions
and conditions of this Indenture or any other Note Document (or, if a Default or
Event of Default has occurred, describing all such Defaults or Events of Default
of which he or she may have knowledge and what action the Company is taking or
proposes to take with respect thereto) and that to the best of his or her
knowledge no event has occurred and remains in existence by reason of which

written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 or, if any such violation has occurred,
specifying the nature and period of existence thereof, it being understood that
such accountants shall not be liable directly or indirectly to any Person for
any failure to obtain knowledge of any such violation.

      (c)   So long as any of the Notes are outstanding, the Company will

of Default and what action the Company is taking or proposes to take with
respect thereto.

to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

may lawfully do so) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company and

            (10)  the incurrence by the Company of Third Party Subordinated
      Indebtedness; provided, that:

                  (a)   the net proceeds of the Third Party Subordinated
            Indebtedness are applied:

                        (i)   to acquire all or substantially all of the assets
                  of, or any Equity Interests in, a business that constitutes a
                  Permitted Business; provided, that in the case of an
                  acquisition of Equity Interests, the business is or becomes a
                  Subsidiary of the Company and a Guarantor concurrently with
                  such acquisition;

                        (ii)  to make a capital expenditure;

                        (iii) to acquire other assets that are not classified as
                  current assets under GAAP and that are used or useful in a
                  Permitted Business; or

                        (iv)  any combination of the foregoing; and

                                       71
<PAGE>

                  (b)   the Fixed Charge Coverage Ratio for the Company's most
            recently ended four full fiscal quarters for which internal
            financial statements are available immediately preceding the date on
            which the Third Party Subordinated Indebtedness is incurred would
            have been at least 2.0 to 1.0, determined on a Pro Forma basis as if
            the Third Party Subordinated Indebtedness had been incurred at the
            beginning of such period and the proceeds therefrom had been applied
            as intended to be applied (but without giving effect to the
            completion of any construction projects unless actual completion has
            been achieved).

      The Company will not incur, and will not permit any Subsidiary to incur,
any Indebtedness (including Permitted Debt) that is contractually subordinated
in right of payment to any other Indebtedness of the Company or such Subsidiary
unless such Indebtedness is also contractually subordinated in right of payment
to the Secured Obligations on substantially identical terms or on terms that are
more favorable to the holders of the Secured Obligations; provided, however,
that no Indebtedness will be deemed to be contractually subordinated in right of
payment to any other Indebtedness of the Company or any of its Subsidiaries
solely by virtue of being unsecured or by virtue of being secured on a junior
basis.

      For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (10) above,
the Company will be permitted to classify such item of Indebtedness on the date
of its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this Section 4.09. The accrual of
interest, the accretion or amortization of original issue discount, the payment
of interest on any Indebtedness in the form of additional Indebtedness with the
same terms, and the payment of dividends on Disqualified Stock in the form of
additional shares of the same class of Disqualified Stock will not be deemed to
be an incurrence of Indebtedness or an issuance of Disqualified Stock for
purposes of this covenant. Notwithstanding any other provision of this
covenant, the maximum amount of Indebtedness that the Company or any Subsidiary
may incur pursuant to this covenant shall not be deemed to be exceeded solely as
a result of fluctuations in exchange rates or currency values.

Section 4.10 Asset Sales.

      The Company will not, and will not permit any of its Subsidiaries to,
consummate any Asset Sale unless:

            (1)   except with respect to an Asset Sale made pursuant to an
      Existing Purchase Option, the Company (or any of its Subsidiaries, as the
      case may be) receives consideration at the time of the Asset Sale at
      least equal to the Fair Market Value of the assets or Equity Interests
      issued or sold or otherwise disposed of;

            (2)   at least 90% of the consideration received in the Asset Sale
      by the Company or such Subsidiary is in the form of cash. For purposes of
      this provision, each of the following will be deemed to be cash:

                  (a)   any liabilities, as shown on the Company's most recent
            consolidated balance sheet, of the Company or any of its
            Subsidiaries (other than contingent liabilities and liabilities that
            are by their terms subordinated to the Notes or any Subsidiary
            Guarantee) that are assumed by the transferee of any such assets
            pursuant to a customary novation or similar agreement that releases
            the Company or such Subsidiary from further liability;

                                       72
<PAGE>

                  (b)   any securities, notes or other obligations received by
            the Company or any such Subsidiary from such transferee that are
            promptly, subject to ordinary settlement periods, converted by the
            Company or such Subsidiary into cash, to the extent of the cash
            received in that conversion; and

                  (c)   in connection with the exercise by a purchaser of an
            Existing Purchase Option, any amount owed by the Company or the
            applicable Subsidiary to the purchaser under the agreement
            containing such Existing Purchase Option that is set off by the
            purchaser against the purchase price;

            (3)   if the assets disposed of in such Asset Sale include any
      component of a Facility that is necessary for the operation of such
      Facility, the Asset Sale involves the disposition of such Facility as a
      whole; and

            (4)   if the Asset Sale involves the sale of a Facility or all or
      substantially all the assets of a Facility, (a) such Asset Sale is to a
      Person other than an Affiliate of the Company, and (b) all necessary
      amendments are made to those Major Project Documents applicable to such
      Facility to remove such Facility from the scope of such Major Project
      Documents.

      The Company and its Subsidiaries will be required to use the Net Proceeds
from any Asset Sale, Casualty Event or Condemnation Event to make an offer (an
"Asset Sale Offer"):

                  (1)   first, to all holders of First Priority Notes and all
            holders of other First Priority Lien Obligations (to the extent
            required under the applicable First Priority Lien Documents) to
            purchase, prepay or redeem the maximum principal amount of First
            Priority Notes and such other First Priority Lien Obligations that
            may he purchased, prepaid or redeemed out of such Net Proceeds
            (taking into account any mandatory purchase, prepayment or
            redemption of First Priority Lien Obligations required under any
            First Priority Lien Document);

                  (2)   second, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations (and any mandatory
            purchase, prepayment or redemption of First Priority Lien
            Obligations) in accordance with clause (1) above, to all holders of
            Second Priority Notes and all holders of other Second Priority Lien
            Obligations (to the extent required under the applicable Second
            Priority Lien Documents) to purchase, prepay or redeem the maximum
            principal amount of Second Priority Notes and such other Second
            Priority Lien Obligations that may be purchased, prepaid or redeemed
            out of such remaining Net Proceeds (taking into account any
            mandatory purchase, prepayment or redemption of Second Priority Lien
            Obligations required under any Second Priority Lien Document); and

                  (3)   third, if any such Net Proceeds remain after the offer
            to holders of First Priority Lien Obligations and Second Priority
            Lien Obligations (and any mandatory purchase, prepayment or
            redemption of First Priority Lien Obligations and Second Priority
            Lien Obligations) in accordance with clauses (1) and (2) above, to
            all holders of Notes and all holders of other Third Priority Lien
            Obligations (to the extent required under the applicable Third
            Priority Lien Documents) to purchase, prepay or redeem the maximum
            principal amount of Notes and such other Third Priority Lien
            Obligations that may be purchased, prepaid or redeemed out of such
            remaining Net Proceeds (taking into account any mandatory purchase,
            prepayment or redemption of Third Priority Lien Obligations required
            under any Third Priority Lien Document).

                                       73
<PAGE>

      The Issuers may, at their sole option, make an Asset Sale Offer in
accordance with the priorities described above with the net proceeds from any
sale, lease, conveyance or other disposition of any assets or rights not
constituting an Asset Sale. The offer price in any Asset Sale Offer will be
equal to 100% of the principal amount plus accrued and unpaid interest and
Special Interest, if any, to the date of purchase, and will be payable in cash.
If any of such Net Proceeds remain after consummation of the Asset Sale Offer,
the Company and its Subsidiaries may use those excess Net Proceeds for any
purpose not otherwise prohibited by this Indenture, including the making of
Restricted Payments in accordance with Section 4.07. If the aggregate principal
amount of Notes and other Third Priority Lien Obligations tendered into such
Asset Sale Offer or required to be purchased, prepaid or redeemed exceeds the
amount of Net Proceeds available therefor, the Issuers will purchase, prepay or
redeem Notes and such other Third Priority Lien Obligations on a pro rota basis
based on the principal amount of Notes and such other Third Priority Lien
Obligations tendered (or required to be purchased, prepaid or redeemed), with
such adjustments as may be deemed appropriate by the Company so that only Notes
in denominations of $1,000, or integral multiples thereof, will be purchased,
prepaid or redeemed. The Issuers will comply with the procedures set forth in
Section 3.09 with respect to any Asset Sale Offer.

Section 4.11 Transactions with Affiliates.

      The Company will not, and will not permit any of its Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate of the Company
(each, an "Affiliate Transaction"), unless:

            (1)   the Affiliate Transaction, taken as a whole with all other
      related Affiliate Transactions, is on terms that are no less favorable to
      the Company and its Subsidiaries, taken as a whole, than those that would
      have been obtained in a comparable transaction by the Company or such
      Subsidiary with an unrelated Person; and

            (2)   the Company delivers to the Trustee (other than with respect
      to a Shared Facilities Arrangement between or among the Company and/or any
      of its Subsidiaries):

                  (a)   with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $10.0 million but less than or equal to $25.0 million, a
            resolution of the Board of Directors set forth in an Officer's
            Certificate certifying that such Affiliate Transaction complies with
            this covenant and that such Affiliate Transaction has been approved
            by a majority of the Board of Directors; and

                  (b)   with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $25.0 million, a positive opinion as to the Fair Market
            Value of such Affiliate Transaction issued by an accounting,
            appraisal or investment banking firm of national standing.

      The following items will not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

            (1)   any employment agreement, employee benefit plan, officer and
      director indemnification agreement or any similar arrangement entered into
      by the Company or any of its Subsidiaries in the ordinary course of
      business;

                                       74
<PAGE>
            (2) transactions between or among the Company and/or any of the
Guarantors (other than Shared Facility Arrangements);

            (3) transactions with a Person that is an Affiliate of the Company
(but not a Subsidiary of the Company) solely because the Company owns, directly
or through a Subsidiary, an Equity Interest in, or controls, such Person;

            (4) payment of reasonable directors' fees to Persons who are not
otherwise Affiliates of the Company;

            (5) any issuance of Equity Interests (other than Disqualified Stock)
of the Company to Affiliates of the Company; provided, that such Equity
Interests are included in the Collateral;

            (6) Restricted Payments that do not violate Section 4.07;

            (7) loans or advances to employees in the ordinary course of
business not to exceed $1.0 million in the aggregate at any one time
outstanding;

            (8) Permitted Tax Payments;

            (9) transactions under or pursuant to written agreements with
Affiliates of the Company in place as of the Closing Date or any amendment or
modification thereto, so long as any such amendment or modification meets the
requirements of clause (10) or (11) of this paragraph;

            (10) any amendments or modifications of, or waivers under, any
written agreement described under clause (9) of this paragraph that is not a
Major Project Document; provided, that no such amendment, modification or waiver
alters any such agreement in a manner that is materially adverse to the Holders;

            (11) any amendments or modifications of, or waivers under, any Major
Project Document, which are permitted by Section 4.13 and are on terms that are
no less favorable to the Company or its relevant Subsidiary (as certified to the
Trustee in an Officer's Certificate) than those that would have been obtained in
a comparable transaction by the Company or such Subsidiary with an unrelated
Person; and

            (12) any agreement to do any of the foregoing.

Section 4.12 Liens.

      The Company will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind on any asset now owned or hereafter acquired, except Permitted Liens.

Section 4.13 Business Activities.

      The Company will not, and will not permit any of its Subsidiaries to,
engage in any business other than Permitted Businesses, except to such extent as
would not be material to the Company and its Subsidiaries taken as a whole.

                                       75

<PAGE>

      The Company will, and will cause its Subsidiaries to, perform all their
obligations under the Major Project Documents, and the Company will not, and
will not permit any of its Subsidiaries to, terminate, amend or otherwise
modify, or consent to any termination, amendment or modification of, or grant
any waiver under, any Major Project Document, unless any failure to so perform
or any such termination, amendment, modification or waiver would not, when taken
together with all other such failures to perform, terminations, amendments,
modifications and waivers since the Closing Date, be Materially Adverse, as
evidenced by a certificate of the chief financial officer of the Company;
provided, however, that the provisions of this paragraph will not apply to any
amendment, modification or termination of any Major Project Document required
under this Indenture in connection with an Asset Sale.

      The Company will, and will cause its Subsidiaries to, obtain and maintain
all permits and approvals necessary for the construction and operation of the
Facilities, including applicable exemptions from PUHCA, unless the failure to do
so would not reasonably be expected to have a Material Adverse Effect.

      The Company will not, and will not permit any of its Subsidiaries to, use
or dispose of any hazardous materials or allow any hazardous materials to be
brought onto or stored or used on or transported to or released from the
Facilities, other than in accordance with prudent industry practices and in
compliance with all applicable environmental laws, except to the extent such
non-compliance, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

Section 4.14 Corporate Existence.

      Subject to Article 5, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect:

            (1) its corporate existence, and the corporate, partnership or other
      existence of each of its Subsidiaries, in accordance with the respective
      organizational documents (as the same may be amended from time to time) of
      the Company or any such Subsidiary; and

            (2) the rights (charter and statutory), licenses and franchises of
      the Company and its Subsidiaries; provided, however, that the Company will
      not be required to preserve any such right, license or franchise, or the
      corporate, partnership or other existence of any of its Subsidiaries, if
      the Board of Directors shall determine that the preservation thereof is no
      longer desirable in the conduct of the business of the Company and its
      Subsidiaries, taken as a whole, and that the loss thereof is not adverse
      in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

      (a) Upon the occurrence of a Change of Control, the Issuers will make an
offer (a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an integral multiple of $1,000) of such Holder's Notes at a
purchase price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Special Interest, if any, on the Notes
repurchased, to, but excluding, the date of purchase (the "Change of Control
Payment"), subject to the rights of Holders on the relevant record date to
receive interest due on the relevant interest payment date. Within 30 days
following any Change of Control, the Issuers will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and stating:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.15 and that all Notes tendered will be accepted for payment;

                                       76

<PAGE>

            (2) the purchase price and the purchase date, which shall be no
      earlier than 30 days and no later than 60 days from the date such notice
      is mailed (the "Change of Control Payment Date");

            (3) that any Note not tendered will continue to accrue interest;

            (4) that, unless the Issuers default in the payment of the Change of
      Control Payment, all Notes accepted for payment pursuant to the Change of
      Control Offer will cease to accrue interest after the Change of Control
      Payment Date;

            (5) that Holders electing to have any Notes purchased pursuant to a
      Change of Control Offer will be required to surrender the Notes, with the
      form entitled "Option of Holder to Elect Purchase" on the reverse of the
      Notes completed, to the Paying Agent at the address specified in the
      notice prior to the close of business on the third Business Day preceding
      the Change of Control Payment Date;

            (6) that Holders will be entitled to withdraw their election if the
      Paying Agent receives, not later than the close of business on the second
      Business Day preceding the Change of Control Payment Date, a telegram,
      telex, facsimile transmission or letter setting forth the name of the
      Holder, the principal amount of Notes delivered for purchase, and a
      statement that such Holder is withdrawing his election to have the Notes
      purchased; and

            (7) that Holders whose Notes are being purchased only in part will
      be issued new Notes equal in principal amount to the unpurchased portion
      of the Notes surrendered, which unpurchased portion must be equal to
      $1,000 in principal amount or an integral multiple thereof.

      The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Sections 4.15, the Issuers will comply with the applicable
securities laws and regulations and will not be deemed to have breached their
obligations under this Section 4.15 by virtue of such compliance.

      (b) On the Change of Control Payment Date, the Issuers will, to the extent
lawful:

            (1) accept for payment all Notes or portions thereof properly
      tendered pursuant to the Change of Control Offer;

            (2) deposit with the Paying Agent an amount equal to the Change of
      Control Payment in respect of all Notes or portions of Notes properly
      tendered; and

            (3) deliver or cause to be delivered to the Trustee the Notes so
      properly accepted together with an Officer's Certificate stating the
      aggregate principal amount of Notes or portions of Notes being purchased
      by the Issuers.

      The Paying Agent will promptly mail to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee, at the
written request of the Company, will promptly authenticate and mail (or cause to
be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided,
that each new Note will be in a principal amount of $1,000 or an integral
multiple thereof.

                                       77

<PAGE>

      The Issuers will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date.

      The provisions described above that require the Issuers to make a Change
of Control Offer following a Change in Control will be applicable whether or not
any other provisions of this Indenture are applicable. Except as described above
with respect to a Change in Control, this indenture does not contain provisions
that permit the Holders to require that the Issuers repurchase or redeem the
Notes in event of a takeover, recapitalization or similar transaction.

      (c) Notwithstanding anything to the contrary in this Section 4.15, the
Issuers will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section 4.15 and purchases all Notes properly tendered and not withdrawn under
the Change of Control Offer.

Section 4.16 Limitation on Issuances and Sales of Equity Interests in
Subsidiaries.

      The Company will not, and will not permit any of its Subsidiaries to,
transfer, convey, sell, lease or otherwise dispose of any Equity Interests in
any Subsidiary of the Company to any Person (other than the Company or a
Guarantor), unless:

            (1) such transfer, conveyance, sale, lease or other disposition is
      of all the Equity Interests in such Subsidiary; and

            (2) the Net Proceeds from such transfer, conveyance, sale, lease or
      other disposition are applied in accordance with Section 4.10.

      In addition, the Company will not permit any Subsidiary of the Company to
issue any of its Equity Interests (other than, if necessary, shares of its
Capital Stock constituting directors' qualifying shares) to any Person other
than to the Company or a Guarantor.

Section 4.17 Payments for Consent.

      The Company will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any-consideration to or for the
benefit of any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of any Note Document unless such
consideration is offered to be paid and is paid to all Holders that consent,
waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

Section 4.18 Restrictions on Activities of CalGen Finance.

      CalGen Finance will not hold any material assets, become liable for any
material obligations or engage in any significant business activities; provided,
that CalGen Finance may be a co-obligor or guarantor with respect to
Indebtedness if the Company is an obligor on such Indebtedness and the net
proceeds of such Indebtedness are received by the Company, CalGen Finance or one
or more of the Company's other Subsidiaries.

Section 4.19 Deposit of Revenues.

      The Company will, and will cause its Subsidiaries to, deposit all revenues
received by the Company and its Subsidiaries, within 10 Business Days of receipt
thereof, in the "Revenue Account"

                                       78

<PAGE>

established under the Control Agreement Notwithstanding the foregoing, Excess
Cash Flow may be distributed in accordance with Section 4.07.

Section 4.20 Additional Subsidiaries.

      If the Company or any of its Subsidiaries acquires or creates another
Subsidiary after the Closing Date, then (1) that newly acquired or created
Subsidiary will become a Guarantor and execute a supplemental indenture in the
form of Exhibit G and deliver an Opinion of Counsel reasonably satisfactory to
the Trustee within 30 days of the date on which it was acquired or created, and
(2) all real and personal property of that Subsidiary will become part of the
Collateral within 30 days of the date on which that Subsidiary was acquired or
created pursuant to documentation (including Security Documents, financing
statements, opinions and other documents) reasonably satisfactory to the Trustee
and the Collateral Agent.

Section 4.21 Maintenance of Insurance.

      The Company will, and will cause its Subsidiaries to, maintain with
financially sound and reputable insurance companies, insurance on their property
and assets (including the Collateral), in at least such amounts, with such
deductibles and against at least such risks as is customary for companies of the
same or similar size engaged in the same or similar businesses as those of the
Company and its Subsidiaries and furnish to the Collateral Agent, upon written
request, full information as to such Persons' property and liability insurance
carriers. The Company will, and will cause the Guarantors to, cause all their
insurance policies to name the Secured Parties, as a class, as additional
insureds, with a waiver of subrogation, and shall cause all their property and
casualty policies to name the Collateral Agent as loss payee (together with
other lien holders as their interests may appear), with 30 days notice of
cancellation or material change.

Section 4.22 Changes in Covenants when Notes Rated Investment Grade.

      If on any date following the Closing Date:

            (1) after giving effect to the suspension of covenants (and the
      Event of Default) described below, the Notes are rated Baa3 or better by
      Moody's and BBB- or better by S&P; and

            (2) no Default or Event of Default shall have occurred and then be
      continuing,

then, beginning on that day and subject to the provisions of the following
paragraph, the covenants (and the Event of Default) of this Indenture
specifically listed below will be suspended:

            (a)   Section 4.07 (Restricted Payments);

            (b)   Section 4.08 (Dividend and Other Payment Restrictions
                  Affecting Subsidiaries);

            (c)   Section 4.09 (Incurrence of Indebtedness and Issuance of
                  Preferred Equity);

            (e)   Section 4.10 (Deposit of Revenues);

            (d)   Section 4.13 (Business Activities); and

            (f)   clause (9) under Section 6.01 (Events of Default).

                                       79

<PAGE>

      Notwithstanding the foregoing, if the rating assigned to the Notes by
either Moody's or S&P should subsequently decline to below Baa3 or BBB-,
respectively, the foregoing covenants (and the Event of Default) will be
reinstituted with respect to the Notes as of and from the date of such rating
decline. Calculations under reinstated Section 4.07 will be made as if such
covenant had been in effect since the Closing Date except that no Default will
be deemed to have occurred solely by reason of a Restricted Payment made while
such covenant was suspended.

                                   SUCCESSORS

Section 5.01 Merger, Consolidation, or Sale of Assets.

      The Company will not, directly or indirectly:

            (1)   consolidate or merge with or into another Person (whether or
      not the Company is the surviving corporation); or

            (2)   sell, assign, transfer, convey or otherwise dispose of all or
      substantially all of the properties or assets of the Company and its
      Subsidiaries taken as a whole, in one or more related transactions, to
      another Person; or

            (3)   lease all or substantially all of its properties or assets, in
      one or more related transactions, to any other Person.

This Section 5.01 will not apply to (A) a merger of the Company with an
Affiliate solely for the purpose of reconstituting the Company in another
jurisdiction or (B) any sale, assignment, transfer, conveyance, lease or other
disposition of assets between or among the Company and the Guarantors.

      Notwithstanding the foregoing, the Company is permitted to reorganize as a
corporation in accordance with the procedures established herein, provided, that
the Company shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that such
reorganization is not adverse to Holders (it being recognized that such
reorganization shall not be deemed adverse to the Holders solely because (i) of
the accrual of deferred tax liabilities resulting from such reorganization or
(ii) the successor or surviving corporation (a) is subject to income tax as a
corporate entity or (b) is considered to be an "includable corporation" of an
affiliated group of corporations within the meaning of the Internal Revenue Code
of 1986, as amended or any similar state or local law), and the Company delivers
to the Trustee such other certificates and other documents reasonably requested
by the Trustee in connection therewith.

Section 5.02 Successor Corporation Substituted.

      Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company and its Subsidiaries taken as a whole in a transaction that is
subject to, and that complies with the provisions of, Section 5.01, the
successor corporation formed by such consolidation or into or with which the
Company is merged or to which such sale, assignment, transfer, lease, conveyance
or other disposition is made shall succeed to, and be substituted for (so that
from and after the date of such consolidation, merger, sale, lease, conveyance
or other disposition, the provisions of this Indenture referring to the
"Company" shall refer instead to the successor corporation and not to the
Company), and may exercise every right and power of the Company under this
Indenture with the same effect as if such successor Person had been named as the
Company herein; provided, however, that the predecessor Company shall not be
relieved from the obligation to pay

                                       80
<PAGE>

the principal of and interest on the Notes except in the case of a sale of all
of the Company's assets in a transaction that is subject to, and that complies
with the provisions of, Section 5.01.

                                   ARTICLE 6.
                             DEFAULTS AND REMEDIES

Section 6.01 Events of Default.

      Each of the following is an "Event of Default":

            (1)   default for 30 days in the payment when due of interest on, or
      Special Interest, if any, with respect to, any of the Notes;

      aggregate principal amount of outstanding Notes to comply with any of the
      agreements in this Indenture or the Security Documents;

            (5)   default under any mortgage, indenture or instrument under
      which there may be issued or by which there may be secured or evidenced
      any Indebtedness for money borrowed by the Company or any of its
      Subsidiaries (or the payment of which is guaranteed by the Company or any
      of its Subsidiaries), whether such Indebtedness or guarantee existed on
      the Closing Date or is created after the Closing Date, if that default:

                  (a)   is caused by a failure to pay principal of, or interest
            or premium, if any, on such Indebtedness prior to the expiration of
            the grace period provided in such Indebtedness on the date of such
            default (a "Payment Default"); or

                  (b)   results in the acceleration of such Indebtedness prior
            to its express maturity,

      and, in each case, the principal amount of any such Indebtedness, together
      with the principal amount of any other such Indebtedness under which there
      has been a Payment Default or the maturity of which has been so
      accelerated, aggregates $25.0 million or more, and such default shall not
      have been cured or waived or any such acceleration rescinded, or such
      Indebtedness repaid, within 20 days of the Company or the applicable
      Subsidiary becoming aware of such default;

            (6)   failure by the Company or any of its Subsidiaries to pay final
      judgments aggregating in excess of $25.0 million (excluding those covered
      by insurance), which judgments are not paid, discharged or stayed for a
      period of 60 days;

            (7)   the repudiation by CalGen Holdings, the Company or any of its
      Subsidiaries of any of its obligations under the Security Documents or the
      unenforceability of the Security Documents against CalGen Holdings, the
      Company or any of its Subsidiaries for any reason;

                                       81
<PAGE>

      provided, that such repudiation or unenforceability relates to Collateral
      with a Fair Market Value of $25.0 million or more;

            (8)   except as permitted by this Indenture, any Subsidiary
      Guarantee shall be held in any judicial proceeding to be unenforceable or
      invalid or shall cease for any reason to be in full force and effect or
      any Guarantor, or any Person acting on behalf of any Guarantor, shall deny
      or disaffirm its obligations under its Subsidiary Guarantee, and such
      condition shall not have been cured within 30 days after written notice
      from the Trustee or the Holders of at least 25% in aggregate principal
      amount of outstanding Notes;

            (9)   breach by any Person (other than the Company or any of its
      Subsidiaries) of its obligations under, or termination or failure to be in
      full force and effect of, a Major Project Document (unless such breach,
      termination or failure to be in full force and effect would not, when
      taken together with all other such breaches, terminations or failures
      since the Closing Date (other than those that have been cured as
      contemplated below, including by entering into a replacement agreement),
      be Materially Adverse, as evidenced by an Officer's Certificate of the
      chief financial officer of the Company), unless with respect to any Major
      Project Document such breach is cured, or such Major Project Document is
      replaced with a substantially similar agreement (it being understood that
      (a) an agreement will be considered substantially similar if it would not
      be Materially Adverse and (b) the use of an Affiliate of the Company as
      the counterparty under an agreement replacing the Index Hedge will not by
      itself be considered Materially Adverse), within 60 days (or 120 days with
      respect to the Index Hedge) thereafter; and

            (10)  the Company, any of its Subsidiaries that is a Significant
      Subsidiary or any group of its Subsidiaries that taken together would
      constitute a Significant Subsidiary, pursuant to or within the meaning of
      Bankruptcy Law:

                  (a)   commences a voluntary case,

                  (b)   consents to the entry of an order for relief against it
            in an involuntary case,

                  (c)   consents to the appointment of a custodian of it or for
            all or substantially all of its property,

                  (d)   makes a general assignment for the benefit of its
\            creditors, or

                  (e)   generally is not paying its debts as they become due; or

            (11)  a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                  (a)   is for relief against the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would constitute a Significant
            Subsidiary, in an involuntary case;

                  (b)   appoints a custodian of the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would constitute a Significant
            Subsidiary, or for all or substantially all of the property of the
            Company, any of its Subsidiaries that is a Significant Subsidiary or
            any group of its Subsidiaries that taken together would constitute a
            Significant Subsidiary; or

                                       82
<PAGE>

                  (c)   orders the liquidation of the Company, any of its
            Subsidiaries that is a Significant Subsidiary or any group of its
            Subsidiaries that taken together would constitute a Significant
            Subsidiary;

      and the order or decree remains unstayed and in effect for 60 consecutive
      days;

Section 6.02 Acceleration.

      In the case of an Event of Default specified in clause (10) or (11) of
Section 6.01, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Upon any such declaration, the Notes shall become due and
payable immediately.

      The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium or Special Interest, if
any, that has become due solely because of the acceleration) have been cured or
waived.

Section 6.03 Other Remedies.

      If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest and Special Interest, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

      The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

      Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of the Holders
of all of the Notes, waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Special Interest, if any, or interest
on, the Notes (including in connection with an offer to purchase). Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05 Control by Majority.

      Subject to the provisions of the Collateral Trust Agreement, Holders of a
majority in aggregate principal amount of the then outstanding Notes may direct
the time, method and place of conducting any proceeding for exercising any
remedy available to the Trustee or exercising any trust or power conferred on
it. However, the Trustee may refuse to follow any direction that conflicts with
law or this Indenture, that the Trustee determines may be unduly prejudicial to
the rights of other Holders of Notes or that may involve the Trustee in personal
liability.

                                       83
<PAGE>

Section 6.06 Limitation on Suits.

      Except to enforce the right to receive payment of principal, premium, if
any, or interest or Special Merest, if any, when due, no Holder may pursue any
remedy with respect to this Indenture or the Notes unless:

            (1)   such Holder has previously given the Trustee notice that an
      Event of Default is continuing;

            (2)   Holders of at least 25% in aggregate principal amount of the
      then outstanding Notes have requested that the Trustee pursue the remedy;

            (3)   such Holders have offered the Trustee reasonable security or
      indemnity against any loss, liability or expense;

            (4)   the Trustee has not complied with such request within 60 days
      after the receipt thereof and the offer of security or indemnity; and

            (5)   Holders of a majority in aggregate principal amount of the
      Notes then outstanding have not given the Trustee a direction inconsistent
      with such request within such 60- day period.

      A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Special Interest,
if any, and interest on the Note, on or after the respective due dates expressed
in the Note (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder; provided,
that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution
thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of this Indenture upon any
property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium and Special Interest, if any, and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

      The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor

                                       84
<PAGE>

upon the Notes), its creditors or its property and shall be entitled and
empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee, and in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 out of the estate in any such
proceeding, shall be denied for any reason, payment of the same shall be secured
by a Lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties that the Holders may be entitled to
receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

      Subject to the provisions of the Collateral Trust Agreement, if the
Trustee collects any money pursuant to this Article 6, it shall pay out the
money in the following order;

            First: to the Trustee, its agents and attorneys for amounts due
      under Section 7.07, including payment of all compensation, expense and
      liabilities incurred, and all advances made, by the Trustee and the costs
      and expenses of collection;

            Second: to Holders of Notes for amounts due and unpaid on the Notes
      for principal, premium and Special Interest, if any, and interest,
      ratably, without preference or priority of any kind, according to the
      amounts due and payable on the Notes for principal, premium and Special
      Interest, if any, and interest, respectively; and

            Third: to the Company or to such party as a court of competent
      jurisdiction shall direct.

      The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs,

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of
a Note pursuant to Section 6.07, or a suit by Holders of more than 10% in
aggregate principal amount of the then outstanding Notes.

                                   ARTICLE 7.

Section 7.01 Duties of Trustee.

                                       85
<PAGE>

      (a)   If an Event of Default has occurred and is continuing, the Trustee
will exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

      (b)   Except during the continuance of an Event of Default:

            (1)   the duties of the Trustee will be determined solely by the
      express provisions of this Indenture and the Trustee need perform only
      those duties that are specifically set forth in this Indenture and no
      others, and no implied covenants or obligations shall be read into this
      Indenture against the Trustee; and

            (2)   in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee will examine the certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture (but need not confirm or investigate the accuracy of any
      calculations or other facts stated therein).

      (c)   The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

            (1)   this paragraph does not limit the effect of paragraph (b) of
      this Section 7.01;

            (2)   the Trustee will not be liable for any error of judgment made
      in good faith by a Responsible Officer, unless it is conclusively
      determined by a court of competent jurisdiction that the Trustee was
      negligent in ascertaining the pertinent facts; and

            (3)   the Trustee will not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05.

      (d)   Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section 7.01.

      (e)   No provision of this Indenture will require the Trustee to expend or
risk its own funds or incur any liability. The Trustee will be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holder, unless such Holder has offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense.

      (f)   The Trustee will not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

Section 7.02 Rights of Trustee.

      (a)   The Trustee may conclusively rely upon any document believed by it
to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

      (b)   Before the Trustee acts or refrains from acting, it may require an
Officer's Certificate or an Opinion of Counsel or both. The Trustee will not be
liable for any action it takes or omits to take in

                                       86
<PAGE>

good faith in reliance on such Officer's Certificate or Opinion of Counsel. The
Trustee may consult with counsel and the written advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in
good faith and in reliance thereon.

      (c)   The Trustee may act through its attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due
care.

      (d)   The Trustee will not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

      (e)   Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company will be sufficient if
signed by an Officer of the Company.

      (f)   The Trustee will be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that might be
incurred by it in compliance with such request or direction.

      (g)   In no event shall the Trustee be required to take notice of any
default or breach hereof or any Event of Default hereunder unless and until the
Trustee shall have received from a Holder of a Note or from the Company written
notice of the circumstances constituting the breach, default or Event of Default
and stating that said circumstances constitute an Even of Default hereunder.

      (h)   If the Trustee is acting as Paying Agent and/or Registrar hereunder,
the rights and protections afforded to the Trustee pursuant to this Article 7
will also be afforded to such Paying Agent and Registrar.

Section 7.03 Individual Rights of Trustee.

      The Trustee in its individual or any other capacity may become the owner
or pledgee of Notes and may otherwise deal with the Company or any Affiliate of
the Company with the same rights it would have if it were not Trustee. However,
in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days after determining such conflicting
interest, apply to the SEC for permission to continue as trustee or resign to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. Any Agent may do the same with like rights and duties.
The Trustee is also subject to Sections 7.10 and 7.11.

Section 7.04 Trustee's Disclaimer.

      The Trustee will not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

                                       87
<PAGE>

      If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee will mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium or Special
Interest, if any, or interest on any Note, the Trustee may withhold the notice
if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of the
Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

      (a)   Within 60 days after each May 15 beginning with the May 15 following
the Closing Date, and for so long as Notes remain outstanding, the Trustee will
mail to the Holders of the Notes a brief report dated as of such reporting date
that complies with TIA Section 313(a) (but if no event described in TIA Section
313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also will comply with TIA Section
313(b)(2). The Trustee will also transmit by mail all reports as required by TIA
Section 313(c).

      (b)   A copy of each report at the time of its mailing to the Holders of
Notes will be mailed by the Trustee to the Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with
TIA Section 313(d). The Company will promptly notify the Trustee when the Notes
are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

      (a)   The Company will pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation will not be limited by any law on compensation of a
trustee of an express trust. The Company will reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses will
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

      (b)   The Company and the Guarantors will indemnify the Trustee against
any and all losses, liabilities or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture and any other Note Documents to which it is a party, including the
costs and expenses of enforcing this Indenture and any other Note Documents to
which it is a party against the Company and the Guarantors (including this
Section 7.07) and defending itself against any claim (whether asserted by the
Company, the Guarantors, any Holder or any other Person) or liability, loss or
expense incurred by it in connection with the exercise or performance of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to its negligence or bad faith as finally determined
by a court of competent jurisdiction. The Trustee will notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company will not relieve the Company or any of the Guarantors of
their obligations hereunder. The Company or such Guarantor will defend the claim
and the Trustee will cooperate in the defense. The Trustee may have separate
counsel and the Company will pay the reasonable fees and expenses of such
counsel. Neither the Company nor any Guarantor need pay for any settlement made
without its consent, which consent will not be unreasonably withheld.

      (c)   The obligations of the Company and the Guarantors under this Section
7.07 will survive the satisfaction and discharge of this Indenture.

      (d)   To secure the Company's payment obligations in this Section 7.07,
the Trustee will have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in

                                       88
<PAGE>

trust to pay principal of and interest on particular Notes. Such Lien will
survive the satisfaction and discharge of this Indenture.

      (e)   When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(10) or (11) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

      (f)   The Trustee will comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

Section 7.08 Replacement of Trustee.

      (a)   A resignation or removal of the Trustee and appointment of a
successor Trustee will become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 7.08.

      (b)   The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

            (1)   the Trustee fails to comply with Section 7.10;

            (2)   the Trustee is adjudged a bankrupt or an insolvent or an order
      for relief is entered with respect to the Trustee under any Bankruptcy
      Law;

            (3)   a custodian or public officer takes charge of the Trustee or
      its property; or

            (4)   the Trustee becomes incapable of acting.

      (c)   If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company will promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

      (d)   If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in aggregate principal amount of the then outstanding
Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

      (e)   If the Trustee, after written request by any Holder who has been a
Holder for at least six months, fails to comply with Section 7.10, such Holder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

      (f)   A successor Trustee will deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the
successor Trustee will have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders. The retiring Trustee will promptly transfer all property held by it
as Trustee to the successor Trustee, provided, that all sums owing to the
Trustee hereunder have been paid and subject to the Lien provided for in Section
7.07.

                                       89
<PAGE>

Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the
Company's obligations under Section 7.07 will continue for the benefit of the
retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

      If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act will be the successor Trustee.

Section 7.10 Eligibility; Disqualification.

      There will at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and (i) in the case of the initial Trustee, that also satisfies the
eligibility requirements for a trustee under the TIA and (ii) in the case of any
successor Trustee, that has a combined capital and surplus of at least $100
million as set forth in its most recent published annual report of condition.

      This Indenture will always have a Trustee who satisfies the requirements
of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section
310(b).

Section 7.11 Preferential Collection of Claims Against Company.

      The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

      The Issuers may, at their option at any time, elect to have either Section
8.02 or 8.03 be applied to all outstanding Notes upon compliance with the
conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.02, the Issuers and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be deemed to have been
discharged from their obligations with respect to all outstanding Notes
(including the Subsidiary Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that the Issuers and the Guarantors will be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes
(including the Subsidiary Guarantees), which will thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 and the other Sections of
this Indenture referred to in clauses (1) and (2) below, and to have satisfied
all their other obligations under such Notes, the Subsidiary Guarantees and this
Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following provisions which will survive until otherwise terminated or discharged
hereunder:

                                       90
<PAGE>

            (1)   the rights of Holders of outstanding Notes to receive payments
      in respect of the principal of, or interest or premium or Special
      Interest, if any, on such Notes when such payments are due from the trust
      referred to in Section 8.04;

            (2)   the Issuers' obligations with respect to such Notes under
      Article 2 and Section 4.02;

            (3)   the rights, powers, trusts, duties and immunities of the
      Trustee hereunder and the Issuers' and the Guarantors' obligations in
      connection therewith; and

            (4)   this Article 8.

      Subject to compliance with this Article 8, the Issuers may exercise their
option under this Section 8.02 notwithstanding the prior exercise of their
option under Section 8.03.

Section 8.03 Covenant Defeasance.

      Upon the Issuers' exercise under Section 8.01 of the option applicable to
this Section 8.03, the Issuers and the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from each
of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20 and 4.21 with respect
to the outstanding Notes on and after the date the conditions set forth in
Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes
will thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but will continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes may not be deemed outstanding for accounting purposes). For this purpose,
Covenant Defeasance means that, with respect to the outstanding Notes and
Subsidiary Guarantees, the Issuers and the Guarantors may omit to comply with
and will have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document and
such omission to comply will not constitute a Default or an Event of Default
under Section 6.01, but, except as specified above, the remainder of this
Indenture and such Notes and Subsidiary Guarantees will be unaffected thereby.
In addition, upon the Issuers' exercise under Section 8.01 of the option
applicable to this Section 8.03, subject to the satisfaction of the conditions
set forth in Section 8.04, Sections 6.01(3) through 6.01(5) will not constitute
Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

      In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.02 or 8.03:

            (1)   the Issuers must irrevocably deposit with the Trustee, in
      trust, for the benefit of the Holders, cash in United States dollars,
      non-callable Government Securities, or a combination thereof, in such
      amounts as will be sufficient, in the opinion of a nationally recognized
      investment bank, appraisal firm or firm of independent public accountants,
      to pay the principal of, or interest and premium and Special Interest, if
      any, on the outstanding Notes on the Stated Maturity or on the applicable
      redemption date, as the case may be, and the Issuers must specify whether
      the Notes are being defeased to maturity or to a particular redemption
      date;

                                       91
<PAGE>

            (2)   in the case of an election under Section 8.02, the Issuers
      must have delivered to the Trustee an Opinion of Counsel in the United
      States reasonably acceptable to the Trustee confirming that:

                  (A)   the Issuers have received from, or there has been
            published by, the Internal Revenue Service a ruling; or

                  (B)   since the Closing Date, there has been a change in the
            applicable federal income tax law;

      in either case to the effect that, and based thereon such Opinion of
      Counsel shall confirm that, the Holders of the outstanding Notes will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such Legal Defeasance and will be subject to federal income tax on the
      same amounts, in the same manner and at the same times as would have been
      the case if such Legal Defeasance had not occurred;

            (3)   in the case of an election under Section 8.03, the Issuers
      have delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee confirming that the Holders of the
      outstanding Notes will not recognize income, gain or loss for federal
      income tax purposes as a result of such Covenant Defeasance and will be
      subject to federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such Covenant Defeasance
      had not occurred;

            (4)   no Default or Event of Default shall have occurred and be
      continuing on the date of such deposit (other than a Default or Event of
      Default resulting from the borrowing of funds to be applied to such
      deposit);

            (5)   such Legal Defeasance or Covenant Defeasance will not result
      in a breach or violation of, or constitute a default under, any material
      agreement or instrument to which the Company or any of its Subsidiaries is
      a party or by which the Company or any of its Subsidiaries is bound;

            (6)   the Issuers must deliver to the Trustee an Officer's
      Certificate stating that the deposit was not made by the Issuers with the
      intent of preferring the Holders of Notes over the other creditors of the
      Issuers with the intent of defeating, hindering, delaying or defrauding
      creditors of the Issuers or others; and

            (7)   the Issuers must deliver to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

      Subject to Section 8.06, all money and non-callable Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant
to Section 8.04 in respect of the outstanding Notes will be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Notes of all sums due and to become due thereon in

                                       92
<PAGE>

respect of principal, premium and Special Interest, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

      The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Notes.

      Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Issuers from time to time upon the request of the
Issuers any money or non-callable Government Securities held by them as provided
in Section 8.04 which, in the opinion of a nationally recognized investment
bank, appraisal firm or firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(1)), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance.

Section 8.06 Repayment to Company.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuers, in trust for the payment of the principal of, premium and Special
Interest, if any, or interest on any Note and remaining unclaimed for two years
after such principal, premium and Special Interest, if any, or interest has
become due and payable shall be paid to the Issuers on their request or (if then
held by the Issuers) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Issuers for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Issuers as trustee thereof, will
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which will not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Issuers.

Section 8.07 Reinstatement.

      If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03, as the case may be, by reason of any order or judgment of any court or
Governmental Authority enjoining, restraining or otherwise prohibiting such
application, then the Issuers' and the Guarantors' obligations under this
Indenture, the Notes and the Subsidiary Guarantees will be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.02 or 8.03, as the case may be; provided,
however, that, if the Issuers make any payment of principal of, premium or
Special Interest, if any, or interest on any Note following the reinstatement of
their obligations, the Issuers will be subrogated to the rights of the Holder of
such Note to receive such payment from the money held by the Trustee or Paying
Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

      Notwithstanding Section 9.02, the Issuers, the Guarantors and the Trustee
may, without the consent of any Holder, amend or supplement this Indenture, the
Subsidiary Guarantees or the Notes:

                                       93
<PAGE>

            (1) to cure any ambiguity, defect or inconsistency;

            (2) to provide for uncertificated Notes in addition to or in place
      of certificated Notes;

            (3) to provide for the assumption of the Issuers' obligations to the
      Holders of the Notes by a successor to the Issuers pursuant to Article 5;

            (4) to make any change that would provide any additional rights or
      benefits to the Holders or that does not adversely affect the legal rights
      hereunder of any Holder;

            (5) to comply with requirements of the SEC in order to effect or
      maintain the qualification of this Indenture under the TIA;

            (6) to make, complete or confirm any grant of Collateral permitted
      or required by this Indenture or any of the Security Documents or any
      release of Collateral that becomes effective as set forth in this
      Indenture or any of the Security Documents;

            (7) to conform the text of this Indenture, the Subsidiary
      Guarantees, the Security Documents or the Notes to any provision of the
      "Description of Notes" section contained in the Offering Memorandum to the
      extent that such provision in such "Description of Notes" section was
      intended to be a verbatim recitation of a provision of this Indenture, the
      Subsidiary Guarantees, the Security Documents or the Notes; or

            (8) to allow any Guarantor to execute a supplemental indenture in
      the form of Exhibit G and/or a Subsidiary Guarantee with respect to the
      Notes.

      Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section
7.02, the Trustee will join with the Company and the Guarantors in the execution
of any amended or supplemental indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations
that may be therein contained, but the Trustee will not be obligated to enter
into such amended or supplemental indenture that affects its own rights, duties
or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

      Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15), the Subsidiary Guarantees and the Notes with the consent
of the Holders of at least a majority in aggregate principal amount of the Notes
then outstanding voting as a single class (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or
purchase of, the Notes), and, subject to Sections 6.04 and 6.07, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium or Special Interest, if any, or interest on
the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture, the Subsidiary
Guarantees or the Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes voting as a
single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.08 shall determine
which Notes are considered to be "outstanding" for purposes of this Section
9.02.

                                       94

<PAGE>

      Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02, the Trustee will join
with the Company in the execution of such amended or supplemental indenture
unless such amended or supplemental indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but will not be obligated to, enter into such
amended or supplemental indenture.

      It will not be necessary for the consent of the Holders of Notes under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it is sufficient if such consent approves the substance thereof.

      After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company will mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, will not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver. Subject to Sections 6.04 and 6.07, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

            (1) reduce the principal amount of Notes whose Holders must consent
      to an amendment, supplement or waiver;

            (2) reduce the principal of or change the fixed maturity of any Note
      or alter the provisions with respect to the redemption of the Notes (other
      than the provisions of Sections 3.09, 4.10 and 4.15);

            (3) reduce the rate of or change the time for payment of interest,
      including default interest, on any Note;

            (4) waive a Default or Event of Default in the payment of principal
      of, or premium, interest or Special Interest, if any, on, the Notes
      (except a rescission of acceleration of the Notes by the Holders of at
      least a majority in aggregate principal amount of the then outstanding
      Notes and a waiver of the payment default that resulted from such
      acceleration);

            (5) make any Note payable in money other than that stated in the
      Notes;

            (6) make any change in the provisions of this Indenture relating to
      waivers of Defaults or Events of Default or the rights of Holders of Notes
      to receive payments of principal of, or interest, premium or Special
      Interest, if any, on the Notes;

            (7) waive a redemption payment with respect to any Note (other than
      a payment required under Section 4.10 or Section 4.15);

            (8) release any Guarantor from any of its payment obligations under
      its Subsidiary Guarantee or this Indenture, except in accordance with the
      terms of this Indenture;

                                       95

<PAGE>

            (9) release any portion of the Collateral from the Liens created by
      the Security Documents except as specifically provided for in this
      Indenture and the Security Documents; or

            (10) make any change in the preceding amendment and waiver
      provisions.

Section 9.03 Compliance with Trust Indenture Act.

      Every amendment or supplement to this Indenture or the Notes will be set
forth in an amended or supplemental indenture that complies with the TIA as then
in effect.

Section 9.04 Revocation and Effect of Consents.

      Until an amendment, supplement or waiver becomes effective, a consent to
it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

      The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

      Failure to make the appropriate notation or issue a new Note will not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

      The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental indenture until the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
will be entitled to receive and (subject to Section 7.01) will be fully
protected in relying upon, in addition to the documents required by Section
13.04, an Officer's Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted
by this Indenture.

            (6) the rules for determining priority under any law governing
      relative priorities of Liens:

      (a) all Liens at any time granted by the Company or any Guarantor to
secure any of the Secured Debt within such Class will secure, equally and
ratably, all present and future Secured Obligations within such Class; and

      (b) all proceeds of all Liens at any time granted by the Company or any
Guarantor to secure any of the Secured Debt and other Secured Obligations within
such Class will be allocated and distributed equally and ratably on account of
the Secured Debt and other Secured Obligations within such Class; provided, that
in the absence of an Event of Default, subject to the requirements set forth in
Sections 3.09 and 4.10, the Company and the Guarantors shall be entitled to
utilize cash proceeds of Collateral in the ordinary course of their business.

      The foregoing provision is intended for the benefit of, and will be
enforceable as a third party beneficiary by, each present and future holder of
Secured Obligations within the applicable Class, each present and future Secured
Debt Representative therefor and the Collateral Agent as holder of Secured
Obligations within such Class. The Secured Debt Representative of each future
Series of Secured Debt within a Class will be required to deliver a Sharing

Holders in accordance with Article 4 of the Collateral Trust Agreement, the
Trustee will vote all of such Notes as directed by the Holders of a majority in
aggregate principal amount of the outstanding principal amount of Notes. For
purposes of such direction to the Trustee, Notes registered in the name of, or
Beneficially Owned by, the Company or an Affiliate of the Company will be deemed
not to be outstanding.

First Priority Liens securing First Priority Lien Debt up to the First Priority
Lien Cap and all related First Priority Lien Obligations and (2) all Second
Priority Liens securing Second Priority Lien Debt up to the Second Priority Lien
Cap and all related Second Priority Lien Obligations.

enforceable as a third party beneficiary by, each present and future holder of
First Priority Lien Obligations or Second Priority Lien Obligations, each
present and future First Priority Debt Representative and Second Priority Debt
Representative and the Collateral Agent as holder of First Priority Liens and
Second Priority Liens. No other Person will be entitled to rely on, have the
benefit of or enforce this provision. The Third Priority Debt Representative for
each future Series of Third Priority Lien Debt will be required to deliver a
Lien Priority Confirmation to the collateral agent, each First Priority Debt
Representative and each Second Priority Debt Representative at the time of
incurrence of such Series of Third Priority Lien Debt.

      In addition, the foregoing provision is intended solely to set forth the
relative ranking, as Liens, of the Liens securing Third Priority Lien Debt as
against the First Priority Liens and Second Priority Liens. Neither the Notes
nor any other Third Priority Lien Obligations nor the exercise or enforcement of
any right or remedy for the payment or collection thereof are intended to be, or
will ever be by reason of the foregoing provision, in any respect subordinated,
deferred, postponed, restricted or prejudiced.

Section 10.04 Relative Rights.

      Nothing in the Note Documents will:

            (1) impair, as between the Company and the holders of the Notes, the
      obligation of the Company to pay principal of, premium and interest, if
      any, on the Notes in accordance with their terms or any other obligation
      of the Company or any other obligor under the Note Documents;

            (2) affect the relative rights of holders of Notes as against any
      other creditors of the Company or any Guarantor (other than holders of
      other Secured Obligations);

      that are then due and owing (but not enforce any judgment in respect
      thereof against any Collateral to the extent specifically prohibited by
      the provisions of the Collateral Trust Agreement);

            (4) restrict or prevent any holder of Notes, the Trustee, the
      Collateral Agent or other Person on their behalf from exercising any of
      its rights or remedies upon a Default or Event of Default not specifically
      restricted or prohibited by the Collateral Trust Agreement; or

the Notes or any other Note Obligations, and the right of the holders of the
Notes and such Note Obligations to the benefits and proceeds of the Collateral
Agent's Liens on Collateral shall terminate and be discharged:

            (1) upon satisfaction and discharge of this Indenture in accordance
      with Article 12;

            (2) upon a Legal Defeasance or Covenant Defeasance of the Notes in
      accordance with Article 8; or

            (3) upon payment in full and discharge of all Notes and other Note
      Obligations that are outstanding under this Indenture, due and payable

      discharged.

Upon the occurrence of any of the events described in clauses (1), (2) and (3)
above, the Trustee will authorize the Collateral Agent to release the Liens on
the Collateral securing the Notes.

                              SUBSIDIARY GUARANTEES

Section 11.01 Guarantee.

      (a) Subject to this Article 11 and the limitations set forth in Section
13.07, each of the Guarantors hereby, jointly and severally, unconditionally
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Notes or the obligations of the
Company hereunder or thereunder, that:

            (1) the principal of, premium and Special Interest, if any, and
      interest on the Notes will be promptly paid in full when due, whether at
      maturity, by acceleration, redemption or otherwise, and interest on the
      overdue principal of and interest and Special Interest, if any, on the
      Notes, if any, if lawful, and all other obligations of the Company to the
      Holders or the Trustee hereunder or thereunder will be promptly paid in
      full or performed, all in accordance with the terms hereof and thereof;
      and

            (2) in case of any extension of time of payment or renewal of any
      Notes or any of such other obligations, that same will be promptly paid in
      full when due or performed in accordance with the terms of the extension
      or renewal, whether at stated maturity, by acceleration or otherwise.

      Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

      (b) Subject to the limitations set forth in Section 13.07, the Guarantors
hereby agree that their obligations hereunder are unconditional, irrespective of
the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, the recovery of
any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor. Each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands

                                       99
<PAGE>

whatsoever and covenant that this Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in the Notes and
this Indenture.

         (c)      If any Holder or the Trustee is required by any court or
otherwise to return to the Company, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or
the Guarantors, any amount paid by either to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated
in full force and effect.

         (d)      Each Guarantor agrees that it will not be entitled to any
right of subrogation in relation to the Holders in respect of any obligations
guaranteed hereby until payment in full of all obligations guaranteed hereby.
Each Guarantor further agrees that, as between the Guarantors, on the one hand,
and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6, such obligations (whether or not due
and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 11.02 Limitation on Guarantor Liability.

         Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Subsidiary
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance
for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree
that the obligations of such Guarantor will be limited to the maximum amount
that will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of such Guarantor that are relevant under such laws, and
after giving effect to any collections from, rights to receive contribution from
or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under this Article 11, result in the
obligations of such Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

Section 11.03 Execution and Delivery of Subsidiary Guarantee.

         To evidence its Subsidiary Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Subsidiary Guarantee
substantially in the form attached as Exhibit F will be endorsed by an Officer
of such Guarantor on each Note authenticated and delivered by the Trustee and
that this Indenture will be executed on behalf of such Guarantor by one of its
Officers.

         Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in
Section 11.01 will remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Subsidiary Guarantee.

         If an Officer whose signature is on this Indenture or on the Subsidiary
Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will
be valid nevertheless.

         The delivery of any Note by the Trustee, after the authentication
thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set
forth in this Indenture on behalf of the Guarantors.

                                      100
<PAGE>

         In the event that the Company creates or acquires any Subsidiary after
the Closing Date, if required by Section 4.21, the Company will cause such
Subsidiary to comply with the provisions of Section 4.21 and this Article 11, to
the extent applicable.

Section 11.04 Guarantors May Consolidate, etc., on Certain Terms.

         Except as otherwise provided in Section 11.05, no Guarantor may sell or
otherwise dispose of all or substantially all of its assets to, or consolidate
with or merge with or into (whether or not such Guarantor is the surviving
Person), another Person, other than the Company or another Guarantor, except as
permitted by Section 4.10.

         In case of any such consolidation, merger, sale or conveyance and upon
the assumption by the successor Person, by supplemental indenture in the form of
Exhibit G, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to
be performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed
any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee. All the Subsidiary Guarantees so issued will in
all respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all of such Subsidiary Guarantees had been
issued at the date of the execution hereof.

         Except as set forth in Articles 4 and 5, nothing contained in this
Indenture or in any of the Notes will prevent any consolidation or merger of a
Guarantor with or into the Company or another Guarantor, or will prevent any
sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to the Company or another Guarantor.

Section 11.05 Releases Following Sale of Assets.

         In the event of any sale or other disposition of all or substantially
all of the assets of any Guarantor, by way of merger, consolidation or
otherwise, or a sale or other disposition of all of the Capital Stock of any
Guarantor, in each case to a Person that is not (either before or after giving
effect to such transactions) the Company or a Guarantor, then such Guarantor (in
the event of a sale or other disposition, by way of merger, consolidation or
otherwise, of all of the Capital Stock of such Guarantor) or the Person
acquiring the property (in the event of a sale or other disposition of all or
substantially all of the assets of such Guarantor) will be released and relieved
of any obligations under its Subsidiary Guarantee; provided, that the Net
Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of this Indenture, including without limitation Section
4.10. Upon delivery by the Company to the Trustee of an Officer's Certificate
and an Opinion of Counsel to the effect that such sale or other disposition was
made by the Company in accordance with the provisions of this Indenture,
including without limitation Section 4.10, the Trustee will execute any
documents reasonably required in order to evidence the release of any Guarantor
from its obligations under its Subsidiary Guarantee.

         Any Guarantor not released from its obligations under its Subsidiary
Guarantee will remain liable for the full amount of principal of and interest
and premium and Special Interest, if any, on the Notes and for the other
obligations of any Guarantor under this Indenture as provided in this Article
11.

                           SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

         This Indenture will be discharged and will cease to be of further
effect as to all Notes issued hereunder, when:

                  (1)      either:

                           (a)      all Notes that have been authenticated
         (except lost, stolen or destroyed Notes that have been replaced or paid
         and Notes for whose payment money has theretofore been deposited in
         trust and thereafter repaid to the Issuers) have been delivered to the
         Trustee for cancellation; or

                           (b)      all Notes that have not been delivered to
         the Trustee for cancellation have become due and payable by reason of
         the mailing of a notice of redemption or otherwise or will become due
         and payable within one year and the Issuers have or any Guarantor has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust solely for the benefit of the Holders, cash in
         U.S. dollars, non-callable Government Securities, or a combination
         thereof, in such amounts as will be sufficient without consideration of
         any reinvestment of interest, to pay and discharge the entire
         indebtedness on the Notes not delivered to the Trustee for cancellation
         for principal, premium and Special Interest, if any, and accrued
         interest to the date of maturity or redemption;

                  (2)      no Default or Event of Default has occurred and is
         continuing on the date of such deposit or will occur as a result of
         such deposit and such deposit will not result in a breach or violation
         of, or constitute a default under, any other instrument to which the
         Issuers are or any Guarantor is a party or by which the Issuers are or
         any Guarantor is bound;

                  (3)      the Issuers have or any Guarantor has paid or caused
         to be paid all sums payable by it under this Indenture; and

                  (4)      the Issuers have delivered irrevocable instructions
         to the Trustee under this Indenture to apply the deposited money toward
         the payment of the Notes at maturity or the redemption date, as the
         case may be.

In addition, the Issuers must deliver an Officer's Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

         Notwithstanding the satisfaction and discharge of this Indenture, if
money has been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 12.01, the provisions of Section 12.02 and Section 8.06 will
survive. In addition, nothing in this Section 12.01 will be deemed to discharge
those provisions of Section 7.07, that, by their terms, survive the satisfaction
and discharge of this Indenture.

Section 12.02 Application of Trust Money.

         Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including either Issuer acting

                                      102
<PAGE>

as Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium and Special Interest, if any) and interest for
whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.

         If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 by reason of any legal
proceeding or by reason of any order or judgment of any court or Governmental
Authority enjoining, restraining or otherwise prohibiting such application, the
Company's and any Guarantor's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 12.01; provided, that if the Issuers have made any payment of principal
of, premium or Special Interest, if any, or interest on any Notes because of the
reinstatement of its obligations, the Issuers shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or
Government Securities held by the Trustee or Paying Agent.

         The Company, any Guarantor or the Trustee, by notice to the others, may

         All notices and communications (other than those sent to Holders) will

delivered; five Business Days after being deposited in the mail, postage
prepaid, if mailed; when receipt acknowledged, if sent by facsimile; and the

courier guaranteeing next day delivery to its address shown on the register kept
by the Registrar. Any notice or communication will also be so mailed to any
Person described in TIA Section 313(c), to the extent required by the TIA.
Failure to mail a notice or communication to a Holder or any defect in it will
not affect its sufficiency with respect to other Holders.

         If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

         If the Company mails a notice or communication to Holders, it will mail
a copy to the Trustee and each Agent at the same time.

Section 13.03 Communication by Holders of Notes with Other Holders of Notes.

         Holders may communicate pursuant to TIA Section 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The
Company, the Trustee, the Registrar and anyone else shall have the protection of
TIA Section 312(c).

Section 13.04 Certificate and Opinion as to Conditions Precedent.

         Upon any request or application by the Company to the Trustee to take
any action under this Indenture, the Company shall furnish to the Trustee:

                  (1)      an Officer's Certificate in form and substance
         reasonably satisfactory to the Trustee (which must include the
         statements set forth in Section 13.05) stating that, in the opinion of
         the signers, all conditions precedent and covenants, if any, provided
         for in this Indenture relating to the proposed action have been
         satisfied; and

                                      104
<PAGE>

                  (2)      an Opinion of Counsel in form and substance
         reasonably satisfactory to the Trustee (which must include the
         statements set forth in Section 13.05) stating that, in the opinion of
         such counsel, all such conditions precedent and covenants have been
         satisfied.

Section 13.05 Statements Required in Certificate or Opinion.

         Each certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture (other than a certificate provided
pursuant to TIA Section 314(a)(4)) must comply with the provisions of TIA
Section 314(e) and must include:

                  (1)      a statement that the Person making such certificate
         or opinion has read such covenant or condition;

                  (2)      a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (3)      a statement that, in the opinion of such Person, he
         or she has made such examination or investigation as is necessary to
         enable him or her to express an informed opinion as to whether or not
         such covenant or condition has been satisfied; and

                  (4)      a statement as to whether or not, in the opinion of
         such Person, such condition or covenant has been satisfied.

Section 13.06 Rules by Trustee and Agents.

         The Trustee may make reasonable rules for action by or at a meeting of
Holders. The Registrar or Paying Agent may make reasonable rules and set
reasonable requirements for its functions.

Section 13.07 Non-Recourse; No Personal Liability of Directors, Officers,
Employees and Stockholders.

         Notwithstanding anything to the contrary set forth in this Indenture,
the Notes, any Security Document or any other Note Document, the Notes and the
Subsidiary Guarantees are non-recourse secured obligations of the Company and
Guarantors, respectively. The only recourse a Holder will have with respect to
the payment of principal of, or interest or premium on, the Notes (whether under
the Indenture or the Notes, or pursuant to the Subsidiary Guarantees) will be
enforcement of its rights against CalGen Finance under this Indenture or against
the Collateral pursuant to the Security Documents. The Holders will have no
recourse to the equity or assets of the Excluded Subsidiary.

         No director, officer, employee, incorporator, stockholder, or partner
of the Company or any of its Subsidiaries, as such, will have any liability for
any obligations of the Issuers or any of its Subsidiaries under the Notes, this
Indenture, the Subsidiary Guarantees or the Security Documents, or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
The waiver may not be effective to waive liabilities under the federal
securities laws.

Section 13.08 Governing Law.

         THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO
CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES

                                      105
<PAGE>

WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

Section 13.09 No Adverse Interpretation of Other Agreements.

         This Indenture may not be used to interpret any other indenture, loan
or debt agreement of the Company or its Subsidiaries or of any other Person. Any
such indenture, loan or debt agreement may not be used to interpret this
Indenture.

Section 13.10 Successors.

         All agreements of the Issuers in this Indenture and the Notes will bind
their respective successors. All agreements of the Trustee in this Indenture
will bind its successors. All agreements of each Guarantor in this Indenture
will bind its successors, except as otherwise provided in Section 11.05.

Section 13.11 Severability.

         In case any provision in this Indenture or in the Notes is invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions will not in any way be affected or impaired thereby.

Section 13.12 Counterpart Originals.

         The parties may sign any number of copies of this Indenture. Each
signed copy will be an original, but all of them together represent the same
agreement.

         Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

                  (1)      INTEREST. Calpine Generating Company, LLC, a Delaware
         limited liability company (the "Company"), and CalGen Finance Corp., a
         Delaware corporation ("CalGen Finance" and, together with the Company,
         the "Issuers"), jointly and severally promise to pay interest on the
         principal amount of this Note at the Applicable Third Priority LIBOR
         Rate (as defined below) per annum from March 23,2004 until maturity and
         will pay the Special Interest, if any, payable pursuant to the
         Registration Rights Agreement referred to below. The Issuers will pay
         interest and Special Interest, if any, semiannually in arrears on April
         1 and October 1 of each year or, if any such day is not a Business Day,
         on the next succeeding Business Day (each, an "Interest Payment Date").
         Interest on the Notes will accrue from the most recent date to which
         interest has been paid or, if no interest has been paid, from the date
         of issuance; provided, that if there is no existing Default in the
         payment of interest, and if this Note is authenticated between a record
         date referred to on the face hereof and the next succeeding Interest
         Payment Date, interest shall accrue from such next succeeding Interest
         Payment Date; provided, further, that the first Interest Payment Date
         will be October 1, 2004. The Issuers will pay interest (including
         post-petition interest in any proceeding under any Bankruptcy Law) on
         overdue principal and premium, if any, from time to time on demand at a
         rate that is 1 % per annum in excess of the rate then in effect. The
         Issuers will pay interest (including post-petition interest in any
         proceeding under any Bankruptcy Law) on overdue installments of
         interest and Special Interest (without regard to any applicable grace
         periods) from time to time on demand at the same rate to the extent
         lawful. Interest will be computed on the basis of a 360-day year of
         twelve 30-day months.

                  "Applicable Third Priority LIBOR Rate" means, for each six
         month interest period, 900 basis points over the rate determined by the
         Company (notice of such rate to be sent to the Trustee by the Company
         on the date of determination thereof) equal to the greater of (x)
         1.250% or (y) the applicable British Bankers' Association LIBOR rate
         for deposits in U.S. dollars for a period of six months as reported by
         any generally recognized financial information service as of 11:00 a.m.
         (London time) two Business Days prior to the first day of such interest
         period;

                                  EXHIBIT A-1-3

<PAGE>

         provided, that, if no such British Bankers' Association LIBOR rate is
         available to the Company, the Applicable Third Party LIBOR Rate for the
         relevant interest period shall instead be the rate at which Morgan
         Stanley Senior Funding, Inc. or one of its affiliate banks offers to
         place deposits in U.S. dollars with first-class banks in the London
         interbank market for a period of six months as of approximately 11:00
         a.m. (London time) two Business Days prior to the first day of such
         interest period, in amounts equal to $1.0 million.

                  (2)      METHOD OF PAYMENT. The Company will pay interest on
         the Notes (except defaulted interest) and Special Interest, if any, to
         the Persons who are registered Holders of Notes at the close of
         business on the March 15 or September 15 immediately preceding the
         Interest Payment Date, even if such Notes are canceled after such
         record date and on or before such Interest Payment Date, except as
         provided in Section 2.12 of the Indenture with respect to defaulted
         interest. The Notes will be payable as to principal, premium, interest
         and Special Interest, if any, at the office or agency of the Company
         maintained for such purpose within or without the City and State of New
         York, or, at the option of the Company, payment of interest and Special
         Interest, if any, may be made by check mailed to the Holders at their
         addresses set forth in the register of Holders; provided, that payment
         by wire transfer of immediately available funds will be required with
         respect to principal of, and interest, premium and Special Interest, if
         any, on, all Global Notes and all other Notes the Holders of which will
         have provided wire transfer instructions to the Company or the Paying
         Agent. Such payment will be in such coin or currency of the United
         States of America as at the time of payment is legal tender for payment
         of public and private debts.

                  (3)      PAYING AGENT AND REGISTRAR. The Company, on behalf of
         itself and CalGen Finance, will maintain an office or agency where
         Notes may be presented for registration of transfer or for exchange
         ("Registrar") and an office or agency where Notes may be presented for
         payment ("Paying Agent"). The Registrar will keep a register of the
         Notes and of their transfer and exchange. The Issuers may appoint one
         or more co-registrars and one or more additional paying agents. The
         term "Registrar" includes any co-registrar and the term "Paying Agent"
         includes any additional paying agent. The Issuers may change any Paying
         Agent or Registrar without notice to any Holder. The Company will
         notify the Trustee in writing of the name and address of any Agent not
         a party to the Indenture. If the Issuers fail to appoint or maintain
         another entity as Registrar or Paying Agent, the Trustee shall act as
         such. The Company or any of its Subsidiaries may act as Paying Agent or
         Registrar. The Issuers initially appoint The Depository Trust Company
         to act as Depositary with respect to the Global Notes. The Issuers
         initially appoint the Trustee to act as the Registrar and Paying Agent
         and to act as Custodian with respect to the Global Notes.

                  (4)      INDENTURE. The Company issued the Notes under a Third
         Priority Indenture, dated as of March 23,2004 (the "Indenture"), among
         the Issuers, the Guarantors and the Trustee. The terms of the Notes
         include those stated in the Indenture and those made part of the
         Indenture by reference to the Trust Indenture Act of 1939, as amended
         (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to all such
         terms, and Holders are referred to the Indenture and such Act for a
         statement of such terms. To the extent any provision of this Note
         conflicts with the express provisions of the Indenture, the provisions
         of the Indenture shall govern and be controlling. The Notes are secured
         obligations of the Company and CalGen Finance limited to $680.0 million
         in aggregate principal amount. The Notes are secured on a
         third-priority basis, Equally and Ratably with all other Third Priority
         Lien Obligations, by (a) a security interest in all the assets of the
         Company and the Guarantors other than Excluded Assets, and (b) a pledge
         of the equity interests in the Company and CalGen Expansion Company,
         LLC, subject to liens securing First Priority Lien Obligations and
         Second Priority Lien Obligations and to other Permitted Prior Liens.

                  (5)      OPTIONAL REDEMPTION. The Notes are not redeemable at
         the option of the Issuers.

                  (6)      MANDATORY REDEMPTION. The Issuers will not be
         required to make mandatory redemption or sinking fund payments with
         respect to the Notes.

                  (7)      REPURCHASE AT OPTION OF HOLDER..

                           (a)      Upon the occurrence of a Change of Control,
         the Issuers will make an offer (a "Change of Control Offer") to each
         Holder to repurchase all or any part (equal to $1,000 or an integral
         multiple of $1,000) of such Holder's Notes at a purchase price in cash
         equal to 101% of the aggregate principal amount thereof plus accrued
         and unpaid interest and Special Interest, if any, on the Notes
         purchased, to, but excluding, the date of purchase, subject to the
         rights of Holders on the relevant record date to receive interest due
         on the relevant interest payment date. Within 30 days following any
         Change of Control, the Issuers will mail a notice to each Holder
         describing the transaction or transactions that constitute the Change
         of Control and stating the procedures governing the Change of Control
         Offer as required by Section 4.15 of the Indenture.

                           (b)      The Issuers will be required to use the Net
         Proceeds from any Asset Sale, Casualty Event or Condemnation Event
         remaining after all required purchases, prepayments and/or redemptions
         of First Priority Lien Obligations and Second Priority Lien Obligations
         to offer to prepay Notes and other Third Priority Lien Obligations (an
         "Asset Sale Offer"). The offer price in any Asset Sale Offer will be
         equal to 100% of the principal amount plus accrued and unpaid interest
         and Special Interest, if any, on the Notes purchased, to, but
         excluding, the date of purchase, and will be payable in cash, subject
         to the rights of Holders on the relevant record date to receive
         interest due on the relevant interest payment date. If the aggregate
         principal amount of Notes and other Third Priority Lien Obligations
         tendered into such Asset Sale Offer (or required to be purchased,
         prepaid or redeemed) exceeds the amount of Net Proceeds available
         therefor, the Trustee will select the Notes and such other Third
         Priority Lien Obligations to be purchased on a pro rata basis.

                  (8)      NOTICE OF REDEMPTION. Notice of redemption will be
         mailed at least 30 days but not more than 60 days before the redemption
         date to each Holder whose Notes are to be redeemed at its registered
         address. Notes in denominations larger than $1,000 may be redeemed in
         part but only in whole multiples of $1,000, unless all of the Notes
         held by a Holder are to be redeemed. On and after the redemption date
         interest ceases to accrue on Notes or portions thereof called for
         redemption.

                  (9)      DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
         registered form without coupons in denominations of $1,000 and integral
         multiples thereof. The transfer of Notes may be registered and Notes
         may be exchanged as provided in the Indenture. The Registrar and the
         Trustee may require a Holder, among other things, to furnish
         appropriate endorsements and transfer documents and the Company may
         require a Holder to pay any taxes and fees required by law or permitted
         by the Indenture. The Company need not exchange or register the
         transfer of any Note or portion of a Note selected for redemption,
         except for the unredeemed portion of any Note being redeemed in part.
         Also, the Company need not exchange or register the transfer of any
         Notes for a period of 15 days before a selection of Notes to be
         redeemed or during the period between a record date and the
         corresponding Interest Payment Date.

                  (10)     PERSONS DEEMED OWNERS. The registered Holder of a
         Note may be treated as its owner for all purposes.

                  (11)     AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
         exceptions and the Collateral Trust Agreement, the Indenture, the
         Subsidiary Guarantees and the Notes may be amended or supplemented with
         the consent of the Holders of at least a majority in aggregate
         principal amount of the Notes then outstanding (including consents
         obtained in connection with a purchase or tender offer or exchange
         offer for Notes) voting as a single class, and any existing default or
         compliance with any provision of the Indenture, the Subsidiary
         Guarantees or the Notes may be waived with the consent of the Holders
         of a majority in principal amount of the Notes then outstanding voting
         as a single class. Without the consent of any Holder, the Indenture,
         the Subsidiary Guarantees and the Notes may be amended or supplemented
         to cure any ambiguity, defect or inconsistency, to provide for
         uncertificated Notes in addition to or in place of certificated Notes,
         to provide for the assumption of the Company's or any Guarantor's
         obligations to Holders of the Notes in case of a merger or
         consolidation, to make any change that would provide any additional
         rights or benefits to the Holders of the Notes or that does not
         adversely affect the legal rights under the Indenture of any such
         Holder, to comply with the requirements of the SEC in order to effect
         or maintain the qualification of the Indenture under the Trust
         Indenture Act, to make, complete or confirm any grant of Collateral
         permitted or required by the Indenture or any of the Security Documents
         or any release of Collateral that becomes effective as set forth in the
         Indenture and the Security Documents, to conform the text of the
         Indenture, the Subsidiary Guarantees, the Security Documents or the
         Notes to any provision of the Description of Notes in the Offering
         Memorandum to the extent such provision of the Description of Notes in
         the Offering Memorandum was intended to be a verbatim recitation of a
         provision of the Indenture, the Subsidiary Guarantees, the Security
         Documents or the Notes, or to allow any Guarantor to execute a
         supplemental indenture in the form of Exhibit G to the Indenture and/or
         a Note Guarantee with respect to the Notes.

                  (12)     DEFAULTS AND REMEDIES. Events of Default include: (i)
         default for 30 days in the payment when due of interest or Special
         Interest, if any, on any of the Notes; (ii) default in the payment when
         due of the principal of or premium, if any, on any of the Notes, (iii)
         failure by the Company or any of its Subsidiaries to comply with
         Section 3.09, 4.10, 4.15 or 4.19 of the Indenture; (iv) failure by the
         Company or any of its Subsidiaries to observe or perform any other
         agreement in the Indenture or the Security Documents for 30 days after
         notice to the Company by the Trustee or the Holders of at least 25% in
         aggregate principal amount of the Notes then outstanding voting as a
         single class; (v) default under certain other agreements relating to
         Indebtedness of the Company and its Subsidiaries which default is
         caused by the failure to pay principal of, or interest or premium, if
         any, on, such Indebtedness, or results in the acceleration of such
         Indebtedness prior to its express maturity; (vi) final judgments for
         the payment of money that remain undischarged for a period of 60 days,
         provided the aggregate amount of such judgments exceeds $25.0 million
         (excluding those covered by insurance); (vii) the repudiation of the
         Security Documents by the Company or a Guarantor or the
         unenforceability of the Security Documents under certain circumstances;
         (viii) except as permitted by the Indenture, any Subsidiary Guarantee
         shall be held in any judicial proceeding to be unenforceable or invalid
         or shall cease for any reason to be in full force and effect or any
         Guarantor or any Person acting on its behalf shall deny or disaffirm
         its obligations under such Guarantor's Subsidiary Guarantee; (ix) the
         breach by any Person (other than the Company and its Subsidiaries) of
         its obligations under, or the termination or failure to be in full
         force of, a Major Project Document, unless such breach when taken
         together with all other such breaches would not be materially adverse
         to the Company and its Subsidiaries taken as a whole; and (x) certain
         events of bankruptcy or insolvency with respect to the Company or any
         of its Significant Subsidiaries. If any Event of

                                  EXHIBIT A-1-6

<PAGE>

         Default occurs and is continuing, the Trustee or the Holders of at
         least 25% in aggregate principal amount of the then outstanding Notes
         may declare all the Notes to be due and payable. Notwithstanding the
         foregoing, in the case of an Event of Default arising from certain
         events of bankruptcy or insolvency, all outstanding Notes will become
         due and payable without further action or notice. Holders may not
         enforce the Indenture or the Notes except as provided in the Indenture
         and the Collateral Trust Agreement. Subject to certain limitations,
         Holders of a majority in principal amount of the then outstanding Notes
         may direct the Trustee in its exercise of any trust or power. The
         Trustee may withhold from Holders of the Notes notice of any continuing
         Default or Event of Default (except a Default or Event of Default
         relating to the payment of principal, interest or premium or Special
         Interest, if any) if it determines that withholding notice is in their
         interest. The Holders of a majority in aggregate principal amount of
         the Notes then outstanding by notice to the Trustee may on behalf of
         the Holders of all of the Notes waive any existing Default or Event of
         Default and its consequences under the Indenture except a continuing
         Default or Event of Default in the payment of principal of, or premium,
         if any, or interest or Special Interest, if any, on, the Notes. The
         Issuers are required to deliver to the Trustee annually a statement
         regarding compliance with the Indenture, and the Issuers are required
         upon becoming aware of any Default or Event of Default, to deliver to
         the Trustee a statement specifying such Default or Event of Default.

                  (13)     TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its
         individual or any other capacity, may make loans to, accept deposits
         from, and perform services for the Company or its Affiliates, and may
         otherwise deal with the Company or its Affiliates, as if it were not
         the Trustee.

                  (14)     NO RECOURSE AGAINST OTHERS. A director, officer,
         employee, incorporator or stockholder of the Company or any Guarantor,
         as such, will not have any liability for any obligations of the Company
         or such Guarantor under the Notes, the Subsidiary Guarantees or the
         Indenture or for any claim based on, in respect of, or by reason of,
         such obligations or their creation. Each Holder by accepting a Note
         waives and releases all such liability. This waiver and release are
         part of the consideration for the issuance of the Notes.

                  (15)     AUTHENTICATION. This Note will not be valid until
         authenticated by the manual signature of the Trustee or an
         authenticating agent.

                  (16)     ABBREVIATIONS. Customary abbreviations may be used in
         the name of a Holder or an assignee, such as: TEN COM (= tenants in
         common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants
         with right of survivorship and not as tenants in common), CUST (=
         Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

                  (17)     ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL
         NOTES AND RESTRICTED DEFINITIVE NOTES. In addition to the rights
         provided to Holders of Notes under the Indenture, Holders of Restricted
         Global Notes and Restricted Definitive Notes will have all the rights
         set forth in the Registration Rights Agreement, dated as of March
         23,2004 (the "Registration Rights Agreement"), among the Company,
         CalGen Finance, the Guarantors and the initial purchaser of the Notes.

                  (18)     CUSIP NUMBERS. Pursuant to a recommendation
         promulgated by the Committee on Uniform Security Identification
         Procedures, the Company has caused CUSIP numbers to be printed on the
         Notes and the Trustee may use CUSIP numbers in notices of redemption as
         a convenience to Holders. No representation is made as to the accuracy
         of such numbers either as

                                  EXHIBIT A-1-7

<PAGE>

         printed on the Notes or as contained in any notice of redemption and
         reliance may be placed only on the other identification numbers placed
         thereon.

                  (19)     NON-RECOURSE. Notwithstanding anything to the
         contrary set forth in the Indenture, this Note, any Security Document
         or any other Note Document, this Note and the Subsidiary Guarantees are
         non-recourse secured obligations of the Company and Guarantors,
         respectively. The only recourse a holder of the Notes will have with
         respect to the payment of principal of, or interest or premium or
         Special Interest, if any, on, this Note (whether under the Indenture or
         the Note, or pursuant to the Subsidiary Guarantees) will be enforcement
         of its rights against CalGen Finance under the Indenture or against

      Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

            (1)   INTEREST. Calpine Generating Company, LLC, a Delaware limited
      liability company (the "Company"), and CalGen Finance Corp., a Delaware
      corporation ("CalGen Finance" and, together with the Company, the
      "Issuers"), jointly and severally promise to pay interest on the principal
      amount of this Note at 11.500% per annum from March 23, 2004 until
      maturity and will pay the Special Interest, if any, payable pursuant to
      the Registration Rights Agreement referred to below. The Issuers will pay
      interest and Special Interest, if any, semiannually in arrears on April 1
      and October 1 of each year or, if any such day is not a Business Day, on
      the next succeeding Business Day (each, an "Interest Payment Date").
      Interest on the Notes will accrue from the most recent date to which
      interest has been paid or, if no interest has been paid, from the date of
      issuance; provided, that if there is no existing Default in the payment of
      interest, and if this Note is authenticated between a record date referred
      to on the face hereof and the next succeeding Interest Payment Date,
      interest shall accrue from such next succeeding Interest Payment Date;
      provided, further, that the first Interest Payment Date will be October
      1,2004. The Issuers will pay interest (including post-petition interest in
      any proceeding under any Bankruptcy Law) on overdue principal and premium,
      if any, from time to time on demand at a rate that is 1% per annum in
      excess of the rate then in effect. The Issuers will pay interest
      (including post-petition interest in any proceeding under any Bankruptcy
      Law) on overdue installments of interest and Special Interest (without
      regard to any applicable grace periods) from time to time on demand at the
      same rate to the extent lawful. Interest will be computed on the basis of
      a 360-day year of twelve 30-day months.

            (2)   METHOD OF PAYMENT. The Company will pay interest on the Notes
      (except defaulted interest) and Special Interest, if any, to the Persons
      who are registered Holders of Notes at the close of business on the March
      15 or September 15 immediately preceding the Interest Payment Date, even
      if such Notes are canceled after such record date and on or before such
      Interest Payment Date, except as provided in Section 2.12 of the Indenture
      with respect to defaulted interest. The Notes will be payable as to
      principal, premium, interest and Special

                                  EXHIBIT A-2-3

<PAGE>

      Interest, if any, at the office or agency of the Company maintained for
      such purpose within or without the City and State of New York, or, at the
      option of the Company, payment of interest and Special Interest, if any,
      may be made by check mailed to the Holders at their addresses set forth in
      the register of Holders; provided, that payment by wire transfer of
      immediately available funds will be required with respect to principal of,
      and interest, premium and Special Interest, if any, on, all Global Notes
      and all other Notes the Holders of which will have provided wire transfer
      instructions to the Company or the Paying Agent. Such payment will be in
      such coin or currency of the United States of America as at the time of
      payment is legal tender for payment of public and private debts.

            (3)   PAYING AGENT AND REGISTRAR. The Company, on behalf of itself
      and CalGen Finance, will maintain an office or agency where Notes may be
      presented for registration of transfer or for exchange ("Registrar") and
      an office or agency where Notes may be presented for payment ("Paying
      Agent). The Registrar will keep a register of the Notes and of their
      transfer and exchange. The Issuers may appoint one or more co-registrars
      and one or more additional paying agents. The term "Registrar" includes
      any co-registrar and the term "Paying Agent" includes any additional
      paying agent. The Issuers may change any Paying Agent or Registrar without
      notice to any Holder. The Company will notify the Trustee in writing of
      the name and address of any Agent not a party to the Indenture. If the
      Issuers fail to appoint or maintain another entity as Registrar or Paying
      Agent, the Trustee shall act as such. The Company or any of its
      Subsidiaries may act as Paying Agent or Registrar. The Issuers initially
      appoint The Depository Trust Company to act as Depositary with respect to
      the Global Notes. The Issuers initially appoint the Trustee to act as the
      Registrar and Paying Agent and to act as Custodian with respect to the
      Global Notes.

            (4)   INDENTURE. The Company issued the Notes under a Third Priority
      Indenture, dated as of March 23,2004 (the "Indenture"), among the Issuers,
      the Guarantors and the Trustee. The terms of the Notes include those
      stated in the Indenture and those made part of the Indenture by reference
      to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
      77aaa-77bbbb). The Notes are subject to all such terms, and Holders are
      referred to the Indenture and such Act for a statement of such terms. To
      the extent any provision of this Note conflicts with the express
      provisions of the Indenture, the provisions of the Indenture shall govern
      and be controlling. The Notes are secured obligations of the Company and
      CalGen Finance limited to $150.0 million in aggregate principal amount.
      The Notes are secured on a third-priority basis, Equally and Ratably with
      all other Third Priority Lien Obligations, by (a) a security interest in
      all the assets of the Company and the Guarantors other than Excluded
      Assets, and (b) a pledge of the equity interests in the Company and CalGen
      Expansion Company, LLC, subject to liens securing First Priority Lien

      option of the Issuers.

            (6)   MANDATORY REDEMPTION. The Issuers will not be required to make

      repurchase all or any part (equal to $1,000 or an integral multiple of
      $1,000) of such Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest

      purchase, subject to the rights of Holders on the relevant record date to

      following any Change of Control, the Issuers will mail a notice to each
      Holder describing the transaction or transactions that constitute the
      Change of Control and stating the procedures governing the Change of
      Control Offer as required by Section 4.15 of the Indenture.

                  (b)   The Issuers will be required to use the Net Proceeds
      from any Asset Sale, Casualty Event or Condemnation Event remaining after
      all required purchases, prepayments and/or redemptions of First Priority
      Lien Obligations and Second Priority Lien Obligations to offer to prepay
      Notes and other Third Priority Lien Obligations (an "Asset Sale Offer").
      The offer price in any Asset Sale Offer will be equal to 100% of the
      principal amount plus accrued and unpaid interest and Special Interest, if
      any, on the Notes purchased, to, but excluding, the date of purchase, and
      will be payable in cash, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      If the aggregate principal amount of Notes and other Third Priority Lien
      Obligations tendered into such Asset Sale Offer (or required to be
      purchased, prepaid or redeemed) exceeds the amount of Net Proceeds
      available therefor, the Trustee will select the Notes and such other Third
      Priority Lien Obligations to be purchased on a pro rata basis.

            (8)   NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address. Notes in
      denominations larger than $1,00.0 may be redeemed in part but only in
      whole multiples of $1,000, unless all of the Notes held by a Holder are to
      be redeemed. On and after the redemption date interest ceases to accrue on
      Notes or portions thereof called for redemption.

            (9)   DENOMINATIONS, TRANSFER, EXCHANGE, The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples
      thereof. The transfer of Notes may be registered and Notes may be

      require a Holder, among other things, to furnish appropriate endorsements
      and transfer documents and the Company may require a Holder to pay any
      taxes and fees required by law or permitted by the Indenture. The Company
      need not exchange or register the transfer of any Note or portion of a
      Note selected for redemption, except for the unredeemed portion of any
      Note being redeemed in part. Also, the Company need not exchange or
      register the transfer of any Notes for a period of 15 days before a
      selection of Notes to be redeemed or during the period between a record
      date and the corresponding Interest Payment Date.

      treated as its owner for all purposes.

            (11)  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
      exceptions and the Collateral Trust Agreement, the Indenture, the
      Subsidiary Guarantees and the Notes may be amended or supplemented with

      the Notes then outstanding voting as a single class; (v) default under
      certain other agreements relating to Indebtedness of the Company and its
      Subsidiaries which default is caused by the failure to pay principal of,
      or interest or premium, if any, on, such Indebtedness, or results in the
      acceleration of such Indebtedness prior to its express maturity; (vi)
      final judgments for the payment of money that remain undischarged for a
      period of 60 days, provided the aggregate amount of such judgments exceeds
      $25.0 million (excluding those covered by insurance); (vii) the
      repudiation of the Security Documents by the Company or a Guarantor or the
      unenforceability of the Security Documents under certain circumstances;
      (viii) except as permitted by the Indenture, any Subsidiary Guarantee
      shall be held in any judicial proceeding to be unenforceable or invalid or
      shall cease for any reason to be in full force and effect or any Guarantor
      or any Person acting on its behalf shall deny or disaffirm its obligations
      under such Guarantor's Subsidiary Guarantee; (ix) the breach by any Person
      (other than the Company and its Subsidiaries) of its obligations under, or
      the termination or failure to be in full force of, a Major Project
      Document, unless such breach when taken together with all other such
      breaches would not be materially adverse to the Company and its
      Subsidiaries taken as a whole; and (x) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Significant
      Subsidiaries. If any Event of Default occurs and is continuing, the
      Trustee or the Holders of at least 25% in aggregate principal amount of
      the then outstanding Notes may declare all the Notes to be due and
      payable. Notwithstanding the foregoing, in the case of an Event of Default
      arising from certain events of bankruptcy or insolvency, all outstanding
      Notes will become due and payable without further action or notice.
      Holders may not enforce the Indenture or the Notes except as provided in
      the Indenture and the Collateral Trust Agreement. Subject to certain
      limitations, Holders of a majority in principal amount of the then
      outstanding Notes may direct the Trustee in its exercise of any trust or
      power. The Trustee may withhold from Holders of the Notes notice of any
      continuing Default or Event of Default (except a Default or Event of
      Default relating to the payment of principal, interest or premium or
      Special Interest, if any) if it determines that withholding notice is in
      their interest. The Holders of a majority in aggregate principal amount of
      the Notes then outstanding by notice to the Trustee may on behalf of the
      Holders of all of the Notes waive any existing Default or Event of Default
      and its consequences under the Indenture

                                  EXHIBIT A-2-6
<PAGE>

      except a continuing Default or Event of Default in the payment of
      principal of, or premium, if any, or interest or Special Interest, if any,
      on, the Notes. The Issuers are required to deliver to the Trustee annually
      a statement regarding compliance with the Indenture, and the Issuers are
      required upon becoming aware of any Default or Event of Default, to
      deliver to the Trustee a statement specifying such Default or Event of
      Default.

            (13)  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
      or any other capacity, may make loans to, accept deposits from, and
      perform services for the Company or its Affiliates, and may otherwise deal
      with the Company or its Affiliates, as if it were not the Trustee.

            (14)  NO RECOURSE AGAINST OTHERS. A director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      not have any liability for any obligations of the Company or such
      Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
      for any claim based on, in respect of, or by reason of, such obligations
      or their creation. Each Holder by accepting a Note waives and releases all
      such liability. This waiver and release are part of the consideration for
      the issuance of the Notes.

            (15)  AUTHENTICATION. This Note will not be valid until
      authenticated by the manual signature of the Trustee or an authenticating
      agent.

            (16)  ABBREVIATIONS. Customary abbreviations may be used in the name
      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
      ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
      survivorship and not as tenants in common), CUST (= Custodian), and
      U/G/M/A (= Uniform Gifts to Minors Act).

            (17)  ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
      RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders
      of Notes under the Indenture, Holders of Restricted Global Notes and
      Restricted Definitive Notes will have all the rights set forth in the
      Registration Rights Agreement, dated as of March 23, 2004 (the
      "Registration Rights Agreement"), among the Company, CalGen Finance, the
      Guarantors and the initial purchaser of the Notes.

            (18)  CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
      Committee on Uniform Security Identification Procedures, the Company has
      caused CUSIP numbers to be printed on the Notes and the Trustee may use
      CUSIP numbers in notices of redemption as a convenience to Holders. No
      representation is made as to the accuracy of such numbers either as
      printed on the Notes or as contained in any notice of redemption and
      reliance may be placed only on the other identification numbers placed
      thereon.

            (19)  NON-RECOURSE. Notwithstanding anything to the contrary set
      forth in the Indenture, this Note, any Security Document or any other Note
      Document, this Note and the Subsidiary Guarantees are non-recourse secured
      obligations of the Company and Guarantors, respectively. The only recourse
      a holder of the Notes will have with respect to the payment of principal
      of, or interest or premium or Special Interest, if any, on, this Note
      (whether under the Indenture or the Note, or pursuant to the Subsidiary
      Guarantees) will be enforcement of its rights against CalGen Finance under
      the Indenture or against the Collateral pursuant to the Security
      Documents.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture, the Registration Rights Agreement and the
Security Documents. Requests may be made to:

      Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

            (1)   INTEREST. Calpine Generating Company, LLC, a Delaware limited
      liability company (the "Company"), and CalGen Finance Corp., a Delaware
      corporation ("CalGen Finance" and, together with the Company, the
      "Issuers", jointly and severally promise to pay interest on the principal
      amount of this Note at the Applicable Third Priority LIBOR Rate (as
      defined below) per annum from March 23,2004 until maturity and will pay
      the Special Interest, if any, payable pursuant to the Registration Rights
      Agreement referred to below. The Issuers will pay interest and Special
      Interest, if any, semiannually in arrears on April 1 and October 1 of each
      year or, if any such day is not a Business Day, on the next succeeding
      Business Day (each, an "Interest Payment Date"). Interest on the Notes
      will accrue from the most recent date to which interest has been paid or,
      if no interest has been paid, from the date of issuance; provided, that if
      there is no existing Default in the payment of interest, and if this Note
      is authenticated between a record date referred to on the face hereof and
      the next succeeding Interest Payment Date, interest shall accrue from such
      next succeeding Interest Payment Date; provided, further, that the first
      Interest Payment Date will be October 1, 2004. The Issuers will pay
      interest (including post-petition interest in any proceeding under any
      Bankruptcy Law) on overdue principal and premium, if any, from time to
      time on demand at a rate that is 1% per annum in excess of the rate then
      in effect. The Issuers will pay interest (including post-petition interest
      in any proceeding under any Bankruptcy Law) on overdue installments of
      interest and Special Interest (without regard to any applicable grace
      periods) from time to time on demand at the same rate to the extent
      lawful. Interest will be computed on the basis of a 360-day year of twelve
      30-day months.

                                  EXHIBIT B-1-3

<PAGE>

            "Applicable Third Priority LIBOR Rate" means, for each six month
      interest period, 900 basis points over the rate determined by the Company
      (notice of such rate to be sent to the Trustee by the Company on the date
      of determination thereof) equal to the greater of (x) 1.250% or (y) the
      applicable British Bankers' Association LIBOR rate for deposits in U.S.
      dollars for a period of six months as reported by any generally recognized
      financial information service as of 11:00 a.m. (London time) two Business
      Days prior to the first day of such interest period; provided, that, if no
      such British Bankers' Association LIBOR rate is available to the Company,
      the Applicable Third Party LIBOR Rate for the relevant interest period
      shall instead be the rate at which Morgan Stanley Senior Funding, Inc. or
      one of its affiliate banks offers to place deposits in U.S. dollars with
      first-class banks in the London interbank market for a period of six
      months as of approximately 11:00 a.m. (London time) two Business Days
      prior to the first day of such interest period, in amounts equal to $1.0
      million.

      Until this Regulation S Temporary Global Note is exchanged for one or more
Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to
receive payments of interest hereon; until so exchanged in full, this Regulation
S Temporary Global Note shall in all other respects be entitled to the same
benefits as other Notes under the Indenture.

            (2)   METHOD OF PAYMENT. The Company will pay interest on the Notes
      (except defaulted interest) and Special Interest, if any, to the Persons
      who are registered Holders of Notes at the close of business on the March
      15 or September 15 immediately preceding the Interest Payment Date, even
      if such Notes are canceled after such record date and on or before such
      Interest Payment Date, except as provided in Section 2.12 of the Indenture
      with respect to defaulted interest. The Notes will be payable as to
      principal, premium, interest and Special Interest, if any, at the office
      or agency of the Company maintained for such purpose within or without the
      City and State of New York, or, at the option of the Company, payment of
      interest and Special Interest, if any, may be made by check mailed to the
      Holders at their addresses set forth in the register of Holders; provided,
      that payment by wire transfer of immediately available funds will be
      required with respect to principal of, and interest, premium and Special
      Interest, if any, on, all Global Notes and all other Notes the Holders of
      which will have provided wire transfer instructions to the Company or the
      Paying Agent. Such payment will be in such coin or currency of the United
      States of America as at the time of payment is legal tender for payment of
      public and private debts.

            (3)   PAYING AGENT AND REGISTRAR. The Company, on behalf of itself
      and CalGen Finance, will maintain an office or agency where Notes may be
      presented for registration of transfer or for exchange ("Registrar") and
      an office or agency where Notes may be presented for payment ("Paying
      Agent"). The Registrar will keep a register of the Notes and of their
      transfer and exchange. The Issuers may appoint one or more co-registrars
      and one or more additional paying agents. The term "Registrar" includes
      any co-registrar and the term "Paying Agent" includes any additional
      paying agent. The Issuers may change any Paying Agent or Registrar without
      notice to any Holder. The Company will notify the Trustee in writing of
      the name and address of any Agent not a party to the Indenture. If the
      Issuers fail to appoint or maintain another entity as Registrar or Paying
      Agent, the Trustee shall act as such. The Company or any of its
      Subsidiaries may act as Paying Agent or Registrar. The Issuers initially
      appoint The Depository Trust Company to act as Depositary with respect to
      the Global Notes. The Issuers initially appoint the Trustee to act as the
      Registrar and Paying Agent and to act as Custodian with respect to the
      Global Notes.

            (4)   INDENTURE. The Company issued the Notes under a Third Priority

      made part of the Indenture by reference to the Trust Indenture Act of
      1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are
      subject to all such terms, and Holders are referred to the Indenture and
      such Act for a statement of such terms. To the extent any provision of
      this Note conflicts with the express provisions of the Indenture, the
      provisions of the Indenture shall govern and be controlling. The Notes are
      secured obligations of the Company and CalGen Finance limited to $680.0
      million in aggregate principal amount. The Notes are secured on a
      third-priority basis, Equally and Ratably with all other Third Priority
      Lien Obligations, by (a) a security interest in all the assets of the
      Company and the Guarantors other than Excluded Assets, and (b) a pledge of
      the equity interests in the Company and CalGen Expansion Company, LLC,
      subject to liens securing First Priority Lien Obligations and Second
      Priority Lien Obligations and to other Permitted Prior Liens.

            (5)   OPTIONAL REDEMPTION. The Notes are not redeemable at the
      option of the Issuers.

            (6)   MANDATORY REDEMPTION. The Issuers will not be required to make
      mandatory redemption or sinking fund payments with respect to the Notes.

            (7)   REPURCHASE AT OPTION OF HOLDER..

                  (a)   Upon the occurrence of a Change of Control, the Issuers
      will make an offer (a "Change of Control Offer") to each Holder to
      repurchase all or any part (equal to $1,000 or an integral multiple of
      $1,000) of such Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest
      and Special Interest, if any, on the Notes purchased, to, but excluding,
      the date of purchase, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      Within 30 days following any Change of Control, the Issuers will mail a
      notice to each Holder describing the transaction or transactions that
      constitute the Change of Control and stating the procedures governing the
      Change of Control Offer as required by Section 4.15 of the Indenture.

                  (b)   The Issuers will be required to use the Net Proceeds
      from any Asset Sale, Casualty Event or Condemnation Event remaining after
      all required purchases, prepayments and/or redemptions of First Priority
      Lien Obligations and Second Priority Lien Obligations to offer to prepay
      Notes and other Third Priority Lien Obligations (an "Asset Sale Offer").
      The offer price in any Asset Sale Offer will be equal to 100% of the
      principal amount plus accrued and unpaid interest and Special Interest, if
      any, on the Notes purchased, to, but excluding, the date of purchase, and
      will be payable in cash, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      If the aggregate principal amount of Notes and other Third Priority Lien
      Obligations tendered into such Asset Sale Offer (or required to be
      purchased, prepaid or redeemed) exceeds the amount of Net Proceeds
      available therefor, the Trustee will select the Notes and such other Third
      Priority Lien Obligations to be purchased on a pro rata basis.

            (8)   NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed. On and after the redemption date interest ceases to accrue on
      Notes or portions thereof called for redemption.

      require a Holder, among other things, to furnish appropriate endorsements
      and transfer documents and the Company may require a Holder to pay any
      taxes and fees required by law or permitted by the Indenture. The Company
      need not exchange or register the transfer of any Note or portion of a
      Note selected for redemption, except for the unredeemed portion of any
      Note being redeemed in part. Also, the Company need not exchange or

part for one or more Global Notes only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation
of certificates (accompanied by an Opinion of Counsel, if applicable) required
by Article 2 of the Indenture. Upon exchange of this Regulation S Temporary
Global Note for one or more Global Notes, the Trustee shall cancel this
Regulation S Temporary Global Note.

            (10)  PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (11)  AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
      exceptions and the Collateral Trust Agreement, the Indenture, the
      Subsidiary Guarantees and the Notes may be amended or supplemented with
      the consent of the Holders of at least a majority in aggregate principal
      amount of the Notes then outstanding (including consents obtained in
      connection with a purchase or tender offer or exchange offer for Notes)
      voting as a single class, and any existing default or compliance with any
      provision of the Indenture, the Subsidiary Guarantees or the Notes may be
      waived with the consent of the Holders of a majority in principal amount
      of the Notes then outstanding voting as a single class. Without the
      consent of any Holder, the Indenture, the Subsidiary Guarantees and the
      Notes may be amended or supplemented to cure any ambiguity, defect or
      inconsistency, to provide for uncertificated Notes in addition to or in
      place of certificated Notes, to provide for the assumption of the
      Company's or any Guarantor's obligations to Holders of the Notes in case
      of a merger or consolidation, to make any change that would provide any
      additional rights or benefits to the Holders of the Notes or that does not
      adversely affect the legal rights under the Indenture of any such Holder,
      to comply with the requirements of the SEC in order to effect or maintain
      the qualification of the Indenture under the Trust Indenture Act, to make,
      complete or confirm any grant of Collateral permitted or required by the
      Indenture or any of the Security Documents or any release of Collateral
      that becomes effective as set forth in the Indenture and the Security
      Documents, to conform the text of the Indenture, the Subsidiary
      Guarantees, the Security Documents or the Notes to any provision of the
      Description of Notes in the Offering Memorandum to the extent such
      provision of the Description of Notes in the Offering Memorandum was
      intended to be a verbatim recitation of a provision of the Indenture, the
      Subsidiary Guarantees, the Security Documents or the Notes, or to allow
      any Guarantor to execute a supplemental indenture in the form of Exhibit G
      to the Indenture and/or a Note Guarantee with respect to the Notes.

            (12)  DEFAULTS AND REMEDIES. Events of Default include: (i) default
      for 30 days in the payment when due of interest or Special Interest, if
      any, on any of the Notes; (ii) default in the payment when due of the
      principal of or premium, if any, on any of the Notes, (iii) failure by the
      Company or any of its Subsidiaries to comply with Section 3.09, 4.10, 4.15
      or 4.19 of the Indenture; (iv) failure by the Company or any of its
      Subsidiaries to observe or perform any other agreement in the Indenture or
      the Security Documents for 30 days after notice to the Company by

                                  EXHIBIT B-1-6

<PAGE>

      the Trustee or the Holders of at least 25% in aggregate principal amount
      of the Notes then outstanding voting as a single class; (v) default under
      certain other agreements relating to Indebtedness of the Company and its
      Subsidiaries which default is caused by the failure to pay principal of,
      or interest or premium, if any, on, such Indebtedness, or results in the
      acceleration of such Indebtedness prior to its express maturity, (vi)
      final judgments for the payment of money that remain undischarged for a
      period of 60 days, provided the aggregate amount of such judgments exceeds
      $25.0 million (excluding those covered by insurance); (vii) the
      repudiation of the Security Documents by the Company or a Guarantor or the
      unenforceability of the Security Documents under certain circumstances;
      (viii) except as permitted by the Indenture, any Subsidiary Guarantee
      shall be held in any judicial proceeding to be unenforceable or invalid or
      shall cease for any reason to be in full force and effect or any Guarantor
      or any Person acting on its behalf shall deny or disaffirm its obligations
      under such Guarantor's Subsidiary Guarantee; (ix) the breach by any Person
      (other than the Company and its Subsidiaries) of its obligations under, or
      the termination or failure to be in full force of, a Major Project
      Document, unless such breach when taken together with all other such
      breaches would not be materially adverse to the Company and its
      Subsidiaries taken as a whole; and (x) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Significant
      Subsidiaries. If any Event of Default occurs and is continuing, the
      Trustee or the Holders of at least 25% in aggregate principal amount of
      the then outstanding Notes may declare all the Notes to be due and
      payable. Notwithstanding the foregoing, in the case of an Event of Default
      arising from certain events of bankruptcy or insolvency, all outstanding
      Notes will become due and payable without further action or notice.
      Holders may not enforce the Indenture or the Notes except as provided in
      the Indenture and the Collateral Trust Agreement. Subject to certain
      limitations, Holders of a majority in principal amount of the then
      outstanding Notes may direct the Trustee in its exercise of any trust or
      power. The Trustee may withhold from Holders of the Notes notice of any
      continuing Default or Event of Default (except a Default or Event of
      Default relating to the payment of principal, interest or premium or
      Special Interest, if any) if it determines that withholding notice is in
      their interest. The Holders of a majority in aggregate principal amount of
      the Notes then outstanding by notice to the Trustee may on behalf of the
      Holders of all of the Notes waive any existing Default or Event of Default
      and its consequences under the Indenture except a continuing Default or
      Event of Default in the payment of principal of, or premium, if any, or
      interest or Special Interest, if any, on, the Notes. The Issuers are
      required to deliver to the Trustee annually a statement regarding
      compliance with the Indenture, and the Issuers are required upon becoming
      aware of any Default or Event of Default, to deliver to the Trustee a
      statement specifying such Default or Event of Default.

            (13)  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
      or any other capacity, may make loans to, accept deposits from, and
      perform services for the Company or its Affiliates, and may otherwise deal
      with the Company or its Affiliates, as if it were not the Trustee.

            (14)  No RECOURSE AGAINST OTHERS. A director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      not have any liability for any obligations of the Company or such
      Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
      for any claim based on, in respect of, or by reason of, such obligations
      or their creation. Each Holder by accepting a Note waives and releases all
      such liability. This waiver and release are part of the consideration for
      the issuance of the Notes.

            (15)  AUTHENTICATION. This Note will not be valid until
      authenticated by the manual signature of the Trustee or an authenticating
      agent.

            (20)  INTEREST. Calpine Generating Company, LLC, a Delaware limited
      liability company (the "Company"), and CalGen Finance Corp., a Delaware
      corporation ("CalGen Finance" and, together with the Company, the
      "Issuers"), jointly and severally promise to pay interest on the principal
      amount of this Note at 11.500% per annum from March 23, 2004 until
      maturity and will pay the Special Interest, if any, payable pursuant to
      the Registration Rights Agreement referred to below. The Issuers will pay
      interest and Special Interest, if any, semiannually in arrears on April 1
      and October 1 of each year or, if any such day is not a Business Day, on
      the next succeeding Business Day (each, an "Interest Payment Date").
      Interest on the Notes will accrue from the most recent date to which
      interest has been paid or, if no interest has been paid, from the date of
      issuance; provided, that if there is no existing Default in the payment of
      interest, and if this Note is authenticated between a record date referred
      to on the face hereof and the next succeeding Interest Payment Date,
      interest shall accrue from such next succeeding Interest Payment Date;
      provided, further, that the first Interest Payment Date will be October
      1, 2004. The Issuers will pay interest (including post-petition interest
      in any proceeding under any Bankruptcy Law) on overdue principal and
      premium, if any, from time to time on demand at a rate that is 1% per
      annum in excess of the rate then in effect. The Issuers will pay interest
      (including post-petition interest in any proceeding under any Bankruptcy
      Law) on overdue installments of interest and Special Interest (without
      regard to any applicable grace periods) from time to time on demand at the
      same rate to the extent lawful. Interest will be computed on the basis of
      a 360-day year of twelve 30-day months.

                                 EXHIBIT B-2-3

      Until this Regulation S Temporary Global Note is exchanged for one or more
Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to
receive payments of interest hereon; until so exchanged in full, this Regulation
S Temporary Global Note shall in all other respects be entitled to the same
benefits as other Notes under the Indenture.

            (21)  METHOD OF PAYMENT. The Company will pay interest on the Notes
      (except defaulted interest) and Special Interest, if any, to the Persons
      who are registered Holders of Notes at the close of business on the March
      15 or September 15 immediately preceding the Interest Payment Date, even
      if such Notes are canceled after such record date and on or before such
      Interest Payment Date, except as provided in Section 2.12 of the Indenture
      with respect to defaulted interest. The Notes will be payable as to
      principal, premium, interest and Special Interest, if any, at the office
      or agency of the Company maintained for such purpose within or without the
      City and State of New York, or, at the option of the Company, payment of
      interest and Special Interest, if any, may be made by check mailed to the
      Holders at their addresses set forth in the register of Holders; provided,
      that payment by wire transfer of immediately available funds will be
      required with respect to principal of, and interest, premium and Special
      Interest, if any, on, all Global Notes and all other Notes the Holders of
      which will have provided wire transfer instructions to the Company or the
      Paying Agent. Such payment will be in such coin or currency of the United
      States of America as at the time of payment is legal tender for payment of
      public and private debts.

            (22)  PAYING AGENT AND REGISTRAR. The Company, on behalf of itself
      and CalGen Finance, will maintain an office or agency where Notes may be
      presented for registration of transfer or for exchange ("Registrar") and
      an office or agency where Notes may be presented for payment ("Paying
      Agent"). The Registrar will keep a register of the Notes and of their
      transfer and exchange. The Issuers may appoint one or more co-registrars
      and one or more additional paying agents. The term "Registrar" includes
      any co-registrar and the term "Paying Agent" includes any additional
      paying agent. The Issuers may change any Paying Agent or Registrar without
      notice to any Holder. The Company will notify the Trustee in writing of
      the name and address of any Agent not a party to the Indenture. If the
      Issuers fail to appoint or maintain another entity as Registrar or Paying
      Agent, the Trustee shall act as such. The Company or any of its
      Subsidiaries may act as Paying Agent or Registrar. The Issuers initially
      appoint The Depository Trust Company to act as Depositary with respect to
      the Global Notes. The Issuers initially appoint the Trustee to act as the
      Registrar and Paying Agent and to act as Custodian with respect to the
      Global Notes.

            (23)  INDENTURE. The Company issued the Notes under a Third Priority
      Indenture, dated as of March 23,2004 (the "Indenture"), among the Issuers,
      the Guarantors and the Trustee. The terms of the Notes include those
      stated in the Indenture and those made part of the Indenture by reference
      to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
      77aaa-77bbbb). The Notes are subject to all such terms, and Holders are
      referred to the Indenture and such Act for a statement of such terms. To
      the extent any provision of this Note conflicts with the express
      provisions of the Indenture, the provisions of the Indenture shall govern
      and be controlling. The Notes are secured obligations of the Company and
      CalGen Finance limited to $150.0 million in aggregate principal amount.
      The Notes are secured on a third-priority basis, Equally and Ratably with
      all other Third Priority Lien Obligations, by (a) a security interest in
      all the assets of the Company and the Guarantors other than Excluded
      Assets, and (b) a pledge of the equity interests in the Company and CalGen
      Expansion Company, LLC, subject to liens securing First Priority Lien
      Obligations and Second Priority Lien Obligations and to other Permitted
      Prior Liens.

            (24)  OPTIONAL REDEMPTION. The Notes are not redeemable at the
      option of the Issuers.

            (25)  MANDATORY REDEMPTION. The Issuers will not be required to make
      mandatory redemption or sinking fund payments with respect to the Notes.

            (26)  REPURCHASE AT OPTION OF HOLDER..

                  (a)   Upon the occurrence of a Change of Control, the Issuers
      will make an offer (a "Change of Control Offer") to each Holder to
      repurchase all or any part (equal to $1,000 or an integral multiple of
      $1,000) of such Holder's Notes at a purchase price in cash equal to 101%
      of the aggregate principal amount thereof plus accrued and unpaid interest
      and Special Interest, if any, on the Notes purchased, to, but excluding,
      the date of purchase, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      Within 30 days following any Change of Control, the Issuers will mail a
      notice to each Holder describing the transaction or transactions that
      constitute the Change of Control and stating the procedures governing the
      Change of Control Offer as required by Section 4.15 of the Indenture.

                  (b)   The Issuers will be required to use the Net Proceeds
      from any Asset Sale, Casualty Event or Condemnation Event remaining after
      all required purchases, prepayments and/or redemptions of First Priority
      Lien Obligations and Second Priority Lien Obligations to offer to prepay
      Notes and other Third Priority Lien Obligations (an "Asset Sale Offer").
      The offer price in any Asset Sale Offer will be equal to 100% of the
      principal amount plus accrued and unpaid interest and Special Interest, if
      any, on the Notes purchased, to, but excluding, the date of purchase, and
      will be payable in cash, subject to the rights of Holders on the relevant
      record date to receive interest due on the relevant interest payment date.
      If the aggregate principal amount of Notes and other Third Priority Lien
      Obligations tendered into such Asset Sale Offer (or required to be
      purchased, prepaid or redeemed) exceeds the amount of Net Proceeds
      available therefor, the Trustee will select the Notes and such other Third
      Priority Lien Obligations to be purchased on a pro rata basis.

            (27)  NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed. On and after the redemption date interest ceases to accrue on
      Notes or portions thereof called for redemption.

            (28)  DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples
      thereof. The transfer of Notes may be registered and Notes may be
      exchanged as provided in the Indenture. The Registrar and the Trustee may
      require a Holder, among other things, to furnish appropriate endorsements
      and transfer documents and the Company may require a Holder to pay any
      taxes and fees required by law or permitted by the Indenture. The Company
      need not exchange or register the transfer of any Note or portion of a
      Note selected for redemption, except for the unredeemed portion of any
      Note being redeemed in part. Also, the Company need not exchange or
      register the transfer of any Notes for a period of 15 days before a
      selection of Notes to be redeemed or during the period between a record
      date and the corresponding Interest Payment Date.

      Documents, to conform the text of the Indenture, the Subsidiary
      Guarantees, the Security Documents or the Notes to any provision of the
      Description of Notes in the Offering Memorandum to the extent such
      provision of the Description of Notes in the Offering Memorandum was
      intended to be a verbatim recitation of a provision of the Indenture, the
      Subsidiary Guarantees, the Security Documents or the Notes, or to allow
      any Guarantor to execute a supplemental indenture in the form of Exhibit G
      to the Indenture and/or a Note Guarantee with respect to the Notes.

            (31)  DEFAULTS AND REMEDIES. Events of Default include: (i) default
      for 30 days in the payment when due of interest or Special Interest, if
      any, on any of the Notes; (ii) default in the payment when due of the

      acceleration of such Indebtedness prior to its express maturity; (vi)
      final judgments for the payment of money that remain undischarged for a
      period of 60 days, provided the aggregate amount of such judgments exceeds
      $25.0 million (excluding those covered by insurance); (vii) the
      repudiation of the Security Documents by the Company or a Guarantor or the
      unenforceability of the Security Documents under certain circumstances;
      (viii) except as permitted by the Indenture, any Subsidiary Guarantee
      shall be held in any judicial proceeding to be unenforceable or invalid or

      Subsidiary Guarantee; (ix) the breach by any Person (other than the
      Company and its Subsidiaries) of its obligations under, or the termination
      or failure to be in full force of, a Major Project Document, unless such
      breach when taken together with all other such breaches would not be
      materially adverse to the Company and its Subsidiaries taken as a whole;
      and (x) certain events of bankruptcy or insolvency with respect to the
      Company or any of its Significant Subsidiaries. If any Event of Default
      occurs and is continuing, the Trustee or the Holders of at least 25% in

      the Notes to be due and payable. Notwithstanding the foregoing, in the

      insolvency, all outstanding Notes will become due and payable without
      further action or notice. Holders may not enforce the Indenture or the
      Notes except as provided in the Indenture and the Collateral Trust
      Agreement. Subject to certain limitations, Holders of a majority in
      principal amount of the then outstanding Notes may direct the Trustee in
      its exercise of any trust or power. The Trustee may withhold from Holders
      of the Notes notice of any continuing Default or Event of Default (except
      a Default or Event of Default relating to the payment of principal,
      interest or premium or Special Interest, if any) if it determines that
      withholding notice is in their interest. The Holders of a majority in
      aggregate principal amount of the Notes then outstanding by notice to the
      Trustee may on behalf of the Holders of all of the Notes waive any
      existing Default or Event of Default and its consequences under the
      Indenture except a continuing Default or Event of Default in the payment
      of principal of, or premium, if any, or interest or Special Interest, if
      any, on, the Notes, The Issuers are required to deliver to the Trustee
      annually a statement regarding compliance with the Indenture, and the
      Issuers are required upon becoming aware of any Default or Event of
      Default, to deliver to the Trustee a statement specifying such Default or
      Event of Default.

            (32)  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
      or any other capacity, may make loans to, accept deposits from, and
      perform services for the Company or its Affiliates, and may otherwise deal
      with the Company or its Affiliates, as if it were not the Trustee.

            (33)  NO RECOURSE AGAINST OTHERS. A director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      not have any liability for any obligations of the Company or such
      Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
      for any claim based on, in respect of, or by reason of, such obligations
      or their creation. Each Holder by accepting a Note waives and releases all
      such liability. This waiver and release are part of the consideration for
      the issuance of the Notes.

            (34)  AUTHENTICATION. This Note will not be valid until
      authenticated by the manual signature of the Trustee or an authenticating
      agent.

      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN

      of Notes under the Indenture, Holders of Restricted Global Notes and
      Restricted Definitive Notes will have all the rights set forth in the

            (37)  CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
      Committee on Uniform Security Identification Procedures, the Company has
      caused CUSIP numbers to be printed on the Notes and the Trustee may use
      CUSIP numbers in notices of redemption as a convenience to Holders. No
      representation is made as to the accuracy of such numbers either as
      printed on the Notes or as contained in any notice of redemption and
      reliance may be placed only on the other identification numbers placed

      of, or interest or premium or Special Interest, if any, on, this Note
      (whether under the Indenture or the Note, or pursuant to the Subsidiary
      Guarantees) will be enforcement of its rights against CalGen Finance under
      the Indenture or against the Collateral pursuant to the Security
      Documents.

charge a copy of the Indenture, the Registration Rights Agreement and the
Security Documents. Requests may be made to:

                         [FORM OF SUPPLEMENTAL INDENTURE
                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

      SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as
of_________________, 20__, among_______________________, a______________(the
"Guaranteeing Subsidiary"), Calpine Generating Company, LLC (the "Company"),
CalGen Finance Corp. ("CalGen Finance" and, together with the Company, the
"Issuers"), the other Guarantors (as defined in the Indenture referred to
herein) and Wilmington Trust FSB, as trustee under the Indenture referred to
herein (the "Trustee").

                              W I T N E S S E T H

      WHEREAS, the Issuers have heretofore executed and delivered to the Trustee
a Third Priority Indenture, dated as of March 23, 2004 (the "Indenture"),
providing for the issuance of an aggregate principal amount of $680.0 million of
Third Priority Secured Floating Rate Notes due 2011 and $150.0 million of 11
1/2% Third Priority Secured Notes due 2011 (collectively, the "Notes");

      WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Subsidiary Guarantee"); and

      WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

      NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

      1.    CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

      2.    AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to
provide an unconditional Guarantee on the terms and subject to the conditions
set forth in the Note Guarantee and in the Indenture, including but not limited
to Article 11 thereof, and to become bound as a "Guarantor" under the Indenture.

      3.    NO RECOURSE AGAINST OTHERS. This Subsidiary Guarantee is a
non-recourse secured obligation of the Subsidiary Guarantor. The only recourse a
Holder of Notes will have under the Subsidiary Guarantee is enforcement of its
rights against the Collateral securing the Subsidiary Guarantee pursuant to the
Security Documents. No past, present or future director, officer, employee,
incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such,
shall have any liability for any obligations of the Company or any Guaranteeing
Subsidiary under the Notes, any Subsidiary Guarantee, the Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of the Notes by accepting a
Note waives and releases all such liability. This waiver and release are part of
the consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy.

      4.    NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO

                                   EXHIBIT G-1

THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.

      5.    COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

      6.    EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

      7.    THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Subsidiary and the Company.

      IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above

any other creditor or creditors of the Subordinated Debtor in commencing any
Proceeding against the Subordinated Debtor, [CalGen, CalGen Holdings or any
Guarantor -- ADD ALL THAT ARE NOT SUBORDINATED DEBTORS], but may join in any
Proceeding after it has commenced. At any general meeting of creditors of
Subordinated Debtor, [CalGen, CalGen Holdings or any Guarantor -- ADD ALL THAT
ARE NOT SUBORDINATED DEBTORS], or in the event of any Proceeding, if all Senior
Claims have not been paid in full in cash at such time, the Collateral Agent on
behalf of the Senior Claimants is hereby irrevocably authorized at any such
meeting or in any such Proceeding:

                       (a) To enforce claims comprising Subordinated Debt in the
            name of Junior Claimant, by proof of debt, proof of claim, suit or
            otherwise;

                       (b) To collect any assets of the Subordinated Debtor
            distributed, divided or applied by way of dividend or payment as a
            result of a Proceeding, or such securities issued, on account of
            Subordinated Debt as a result thereof and apply the same, or the
            proceeds of any realization upon the same that the Senior Claimants
            in their discretion elect to effect, to Senior Claims until all
            Senior Claims shall have been paid in full in cash (the Senior
            Claimants hereby agreeing to render any surplus to Junior Claimant
            and/or other subordinated creditors, as their interests appear, or
            to interplead such surplus with a court of competent jurisdiction);
            and

                       (c) To take generally any action in connection with any
            such meeting or proceeding which Junior Claimant might otherwise
            take in respect of the Subordinated Debt and claims relating
            thereto.

                       After the commencement of any such Proceeding, Junior
Claimant may inquire in writing of the Collateral Agent on behalf of the Senior
Claimants whether the respective Senior Claimants intend to exercise the
foregoing rights with respect to the Subordinated Debt. Should the Senior
Claimants fail, at least 20 days before the deadline therefor, either to file a
proof of claim with respect to the Subordinated Debt and to furnish a copy
thereof to Junior Claimant, or to inform Junior Claimant in writing that the
Senior Claimants intend to exercise their rights to assert the Subordinated Debt
in the manner hereinabove provided, Junior Claimant may, but shall not be
required to, proceed to file a proof of claim with respect to the Subordinated
Debt and take such further steps with respect thereto, not inconsistent with
this Article, as Junior Claimant may deem proper.

                       [__].2.6. Upon the occurrence and during the continuation
of an event of default under a Secured Debt Document, Junior Claimant may, but
shall have no obligation to, upon not less than 10 days prior written notice to
the Collateral Agent, purchase all of the outstanding Senior Obligations owing
to the Senior Claimants by irrevocably tendering, in immediately available
funds, full payment of the Purchase Price (as defined below) to the Senior
Claimants:

                       (a) The Purchase Price shall be equal to the total amount
            of Senior Claims at the time of acceleration (assuming such
            obligations have been accelerated);

                                   EXHIBIT H-3
<PAGE>

                  (b) Any such purchase by Junior Claimant shall be without
            warranty by, or recourse to, the Senior Claimants, except with
            respect to the legal and beneficial ownership by the Senior
            Claimants of the Obligations so purchased, free and clear of all
            Liens and rights of others; and

                  (c) Concurrently with any such purchase, the Senior Claimants
            shall forthwith sell, assign, transfer and convey to Junior Claimant
            all of their right, title and interest in and to the Senior
            Obligations, and all Liens and other security interests in favor of
            the Senior Claimants securing the obligations of the Subordinated
            Debtor in connection therewith.

            Section [__].3. Senior Claim Documents. The Junior Claimant
acknowledges that it has been provided with a copy of the Senior Claim Documents
and has read and is familiar with the provisions thereof.

            Section [__].4. Time of Filing. Notwithstanding the time of filing,
attachment or recording of any document or other instrument, it is agreed by
Junior Claimant that any Liens arising under or pursuant to the Senior Claim
Documents shall be senior to any Liens arising in favor of Junior Claimant as
part of or relating to the Subordinated Debt Documents, if any; provided,
however, that nothing herein shall be deemed to permit Junior Claimant to obtain
any such Liens.

            Section [__].5. Wrongful Collections. Should any payment on account
of, or any collateral for any part of, the Subordinated Debt be received by
Junior Claimant in violation of this Article, such payment or collateral shall
be delivered forthwith to the Collateral Agent by the recipient for application
to Senior Claims, in the form received. The Collateral Agent is irrevocably
authorized to supply any required endorsement or assignment which may have been
omitted. Until so delivered, any such payment or collateral shall be held by the
recipient in trust for the Senior Claimants and shall not be commingled with
other funds or property of the recipient.

            Section [__].6. Ownership of Subordinated Debt; Amendment of
Subordinated Debt Documents.

                  [__].6.1. The Junior Claimant represents and warrants that it
is the lawful owner of the Subordinated Debt. Any security interest in the
Junior Claimant's interest in the Subordinated Debt will at all times be subject
to the rights of the Senior Claimants hereunder. The Junior Claimant agrees that
it may not assign all or any portion of the Subordinated Debt or any of its
rights or remedies under the Subordinated Debt Documents unless any assignee
expressly agrees in writing for the benefit of the Collateral Agent that it
takes such Subordinated Debt subject in all respects to the rights of the Senior
Claimants hereunder.

                  [__].6.2. The Subordinated Debt Documents may not be amended
so as to have an adverse effect upon the Senior Claims or the Subordinated
Debtor's ability to pay the Senior Claims at any time.

            Section [__].7. Waivers. The Collateral Agent and the Senior
Claimants are hereby authorized to demand specific performance of this Article,
whether or not the Subordinated Debtor shall have complied with the provisions
hereof applicable to it, at any time when Junior Claimant shall have failed to
comply with any provision hereof applicable to it. Junior Claimant hereby
irrevocably waives any defense based on the adequacy of a remedy at law which
might be asserted as a bar to the remedy of specific performance hereof in any
action brought therefor by the Senior Claimants. Junior Claimant (a) further
waives presentment, notice and protest in connection with all negotiable
instruments

                                   EXHIBIT H-4

<PAGE>

evidencing Senior Claims or Subordinated Debt to which Junior Claimant may be a
party, notice of the acceptance of this Article by the Senior Claimants, notice
of any loan made, extension granted or other action taken in reliance hereon,
and all demands and notices of every kind in connection with this Article,
Senior Claims or time of payment of Senior Claims or Subordinated Debt and (b)
hereby assents to any renewal, extension or postponement of the time of payment
of Senior Claims or any other indulgence with respect thereto, to any increase
in the amount of Senior Claims, to any substitution, exchange or release of
collateral therefor and to the addition or release of any person primarily or
secondarily liable thereon and assents to the provisions of any instrument,
security or other writing evidencing Senior Claims.

            Section [__].8. Subrogation: No Impairment of Subordinated Debtor's
Obligations. Subject to and from and after the Senior Obligations Termination
Date, Junior Claimant shall be subrogated to the rights of the Senior Claimants
to receive payments or distributions of cash, property or securities of the
Subordinated Debtor applicable to the Senior Claims until all amounts owing on
the Subordinated Debt shall be paid in full. For purposes of such subrogation,
no payments or distributions to the Senior Claimants to which Junior Claimant
would be entitled but for the provisions of this Article; and no payments paid
over by Junior Claimant to Senior Claimants pursuant to this Article shall, as
among the Subordinated Debtor, its creditors other than the Senior Claimants,
and Junior Claimant, be deemed to be a payment or distribution on account of the
Subordinated Debt, it being understood that the provisions of this Article are
intended solely for the purpose of defining the relative rights of Junior
Claimant and the Senior Claimants. Nothing contained in this Article is intended
to or shall impair, as between the Subordinated Debtor and Junior Claimant, the
obligation of the Subordinated Debtor, which is absolute and unconditional, to
pay to Junior Claimant the principal of and the premium, if any, and the
interest on the Subordinated Debt, and all other amounts payable by the
Subordinated Debtor under the Subordinated Debt Documents, as and when the same
shall become due and payable, or to affect the relative rights of Junior
Claimant and creditors of Subordinated Debtor other than the Senior Claimants.

            Section [__].9. Reinstatement. The obligations of Junior Claimant
under this Article shall continue to be effective, or be reinstated, as the case
may be, if at any time any payment in respect of any Senior Claim, or any other
